PO Box 1408 Sunderland SR5 9QY is best understood as a mail-processing and correspondence address that can be used on behalf of different organisations, rather than the headquarters or registered office of one single company.
There is strong current evidence connecting the address with Paragon Customer Communications.
In official 2026 documentation, Allianz Global Investors UK Limited instructed shareholders to return documents to Allianz Global Investors UK Limited, c/o Paragon Customer Communications, PO Box 1408, Sunderland SR5 9QY.
The address has also appeared historically in promotional correspondence using the name RHU, including Carling promotions managed with Paragon.
Other organisations, including Currys, have been mentioned by recipients of mail carrying the Sunderland return address, although this should not be treated as proof that Currys currently operates the PO Box.

Who Uses PO Box 1408 Sunderland SR5 9QY?
The main reason PO Box 1408 causes confusion is that it has been associated with more than one organisation.
A PO Box does not necessarily identify the organisation that ultimately sent a letter. Businesses can outsource the printing, distribution, processing and return handling of correspondence to specialist communication providers.
That appears particularly relevant to PO Box 1408.
Paragon Customer Communications
Paragon Customer Communications has one of the strongest documented connections with PO Box 1408 Sunderland SR5 9QY.
Rather than assuming Paragon is the company behind every individual letter, it is more accurate to view it as a communications provider that can process correspondence on behalf of its clients.
This arrangement explains why two people could receive letters carrying the same Sunderland return address while the contents relate to completely different companies.
The company named inside the letter is therefore generally more important than the PO Box printed on the envelope.
Allianz Global Investors
Allianz Global Investors provides particularly strong evidence that PO Box 1408 remains in use.
In documentation concerning the merger of Allianz investment funds, shareholders were instructed to return a proxy form to Allianz Global Investors UK Limited through Paragon Customer Communications at PO Box 1408 Sunderland SR5 9QY. The relevant shareholder meeting took place in February 2026.
This shows that the Sunderland address has been used for legitimate financial correspondence and was not simply an old promotional address that disappeared years ago.
However, it does not mean every letter displaying PO Box 1408 originates from Allianz.
Currys And Currys Care Services
Some recipients have reported receiving mail carrying the Sunderland return address that later appeared to relate to Currys products, appliance cover or care arrangements.
Possible subjects reported around this type of correspondence include:
- Appliance Care Plans
- Product Repair Cover
- Extended Warranty Information
- Renewal Or Expiry Notices
- Previous Product Purchases
- Customer Account Communications
These reports need to be treated carefully.
Currys’ current Care & Repair information lists PO Box 194, Cramlington, NE23 0DA as its postal contact address, rather than PO Box 1408 Sunderland.
Therefore, receiving an older or outsourced letter connected with Currys does not establish that Currys is the present operator of PO Box 1408.
If a letter claims to come from Currys, verify it through Currys’ independently obtained official contact details before making payments or supplying sensitive information.
Other Reported Senders
PO Box 1408 has also appeared in promotional activity involving other brands.
One well-documented example is Carling. Terms for Carling promotions in 2021 instructed participants to send postal claims to RHU, PO Box 1408, Sunderland, SR5 9QY.
The same promotional material identified Paragon as the third-party partner handling parts of the claims process.
This provides useful historical evidence of how the address has operated. A consumer-facing brand can run a promotion while an outsourced communications company handles postal responses using the Sunderland PO Box.
Is PO Box 1408 Sunderland SR5 9QY Still Used In 2026?
Yes. There is reliable evidence that the address was still being used for legitimate correspondence in 2026.
Allianz Global Investors’ 2026 shareholder documentation names PO Box 1408 Sunderland SR5 9QY and Paragon Customer Communications together.
It is important, however, to separate current evidence from historical associations.
For example, Carling’s connection relates to promotions carried out several years earlier. A brand using the address in 2021 does not automatically mean it continues to use it today.
When trying to identify a particular letter, check:
- The Organisation Named Inside The Letter
- The Date Of The Correspondence
- Any Customer Or Policy Reference
- The Reason Given For Contact
- Whether You Have An Existing Relationship With The Organisation
The PO Box alone may not reveal the actual sender.
Why Have I Received A Letter From PO Box 1408 Sunderland?

Receiving unexpected correspondence from Sunderland does not automatically mean something is wrong.
There are several possible explanations.
Appliance Insurance Or Care Plan
If you previously purchased electrical goods or appliances, correspondence could relate to a repair plan, warranty or product-care arrangement.
This may include reminders about an existing agreement, changes to cover, renewals or notices relating to an older product.
Do not assume the letter is genuine simply because you recognise the retailer’s name. Check any plan details against information you already hold and contact the retailer independently when necessary.
Investment Or Shareholder Correspondence
PO Box 1408 has been officially used for investment-related correspondence.
For example, Allianz shareholders were instructed to send proxy forms relating to a fund merger to the Sunderland PO Box through Paragon Customer Communications in 2026.
If you hold investments or previously invested through the organisation named in your letter, this may explain why you have been contacted.
Financial correspondence should still be checked carefully before disclosing personal information or taking action.
Promotional Or Marketing Mail
The address has historically been used for promotions.
Carling’s previous promotional terms show RHU and PO Box 1408 being used for postal prize claims, with Paragon involved in managing the promotion.
A current letter could therefore potentially relate to marketing, customer retention or another outsourced campaign.
Previous Customer Records
Companies sometimes retain customer details for legitimate administrative purposes after the original purchase or interaction.
An unexpected letter might therefore relate to:
- An Old Purchase
- An Expired Service Plan
- A Previous Investment
- Marketing Preferences
- A Competition Or Promotion
- An Account That Has Not Been Used Recently
Check the date and reference numbers before deciding whether the correspondence relates to you.
Is PO Box 1408 Sunderland A Scam?
PO Box 1408 Sunderland SR5 9QY is not, by itself, evidence of a scam.
Official corporate documentation shows legitimate organisations have used the address.
However, a genuine PO Box address does not guarantee that every letter displaying it is genuine. Fraudsters can copy company names, postal addresses and branding from legitimate organisations.
Be more cautious when a letter:
- Demands Immediate Payment
- Requests Your PIN Or Online Banking Password
- Asks For Full Card Details Unexpectedly
- Contains An Unfamiliar Payment Website
- Pressures You To Act Immediately
- Threatens Consequences Without Explaining The Issue Clearly
- Requests Identity Documents Without A Clear Reason
- Provides Contact Information That Differs From Official Sources
Do not make a payment solely because a letter looks professional.
How Can You Check Whether The Letter Is Genuine?
The safest approach is to verify the organisation independently.
Check The Company Named Inside The Letter
Look beyond the return address. The main letter should normally identify the company responsible for the communication and explain why it has contacted you.
Find Official Contact Details Separately
Do not rely exclusively on a telephone number, QR code or website printed in unexpected correspondence.
Search independently for the organisation’s official contact details.
Compare Your Existing Records
If the letter relates to an investment, product purchase, care plan or customer account, compare its reference information with documentation you already possess.
Contact The Organisation
Ask whether it sent the correspondence and whether the reference number shown belongs to a genuine account or campaign.
You should not need to disclose passwords or PINs simply to establish whether correspondence is authentic.
Check Before Paying
If the letter requests money, verify the reason for payment and the payee independently before transferring funds.
What Does RHU PO Box 1408 Sunderland Mean?
Some historical correspondence has displayed RHU alongside PO Box 1408.
The exact commercial meaning of RHU is not always made clear to recipients, which has led to confusion when people attempt to identify it as a standalone company.
Official Carling promotional terms provide useful evidence. They directed postal claims to RHU at PO Box 1408 while also stating that Paragon was involved as the promotional partner.
This suggests RHU has been used within fulfilment or response-handling operations rather than proving it is the name of the ultimate consumer brand behind every letter.
Is RHU The Same As THE RHU LIMITED?
There is no good reason to automatically assume that RHU on Sunderland correspondence means the Companies House business called THE RHU LIMITED.
Companies House currently lists THE RHU LIMITED as an active company with a registered office in Burgess Hill, West Sussex. Its registered business activity is hairdressing and other beauty treatment.
Those details do not establish a connection with PO Box 1408 Sunderland.
The similarity in names alone is not enough evidence to claim THE RHU LIMITED operates the Sunderland address.
Why Do Different Companies Use The Same Sunderland PO Box?
Outsourced customer communications are common.
A large organisation may not print, package, distribute and process every piece of correspondence internally. Instead, a communications provider can manage some of these activities.
A shared processing arrangement can include:
- Printing Customer Letters
- Sending Bulk Correspondence
- Receiving Forms
- Handling Promotional Claims
- Processing Customer Responses
- Managing Returned Mail
- Supporting Shareholder Communications
This explains how Allianz, a promotional campaign and another consumer-facing brand could potentially appear in connection with the same postal address at different times.
The PO Box identifies where correspondence is processed. It does not necessarily identify the organisation whose product, investment or service the letter concerns.
What Have Other Recipients Received From PO Box 1408?
Online discussions about the Sunderland address show that people commonly search for it after seeing it on the back of an unexpected envelope.
Reported subjects have included appliance-related correspondence and product-care arrangements. Historical official records also confirm investment documents and promotional claims using the address.
This means there is no single answer to the question, “What is inside a PO Box 1408 letter?”
The contents depend on the organisation using the mail-processing service at the time.
Rather than guessing from the envelope, check:
- Who Is Named In The Letter
- Why They Say They Are Contacting You
- Whether You Recognise The Account
- Whether Any Reference Number Matches Your Records
- Whether The Organisation Confirms Sending It
What If The Letter Is For A Previous Occupier?
A letter addressed to somebody who no longer lives at your property does not mean their account, debt or agreement has transferred to you.
Avoid opening correspondence addressed to another person unnecessarily.
If appropriate, you can mark the envelope to indicate that the recipient no longer lives at the address and return it through the postal system.
If letters continue arriving, consider contacting the organisation named on the correspondence and explaining that the person is no longer resident at your address.
Do not supply your own financial details simply to prove that another person’s account does not belong to you.
Why Did I Receive A Sunderland Letter In Ireland?

A Sunderland return address does not necessarily mean correspondence is limited to recipients in England or the wider UK.
Businesses can operate centralised fulfilment centres that process correspondence for customers in different regions.
Historical promotional material connected with PO Box 1408 specifically included arrangements for Republic of Ireland participants. Carling’s terms, for example, explained how Republic of Ireland entrants using the postal route would be contacted by Paragon as part of the claim process.
Therefore, an Irish recipient seeing a Sunderland PO Box should focus on identifying the company and purpose of the correspondence rather than assuming the geographic difference makes the letter fraudulent.
How Can You Stop Unwanted Mail From PO Box 1408?
First determine which organisation actually sent the correspondence.
Because multiple organisations can use the same processing address, attempting to opt out through the PO Box alone may not resolve the issue.
You can:
- Identify The Sender – Check the letter for the organisation responsible for the communication
- Contact The Organisation – Ask it to update your marketing preferences where applicable
- Check Previous Accounts – An old customer relationship may explain why your details remain on its records
- Correct Previous Occupier Details – Tell the sender if the person named no longer lives at your address
- Keep Important Correspondence – Do not discard financial, contractual or account-related letters simply because you do not recognise the return address
- Report Suspicious Communications – If you believe someone is impersonating a legitimate company, report the suspected fraud through the appropriate official channels
Remember that opting out of marketing does not necessarily stop essential communications concerning an active contract, investment, account or legal obligation.
Conclusion
PO Box 1408 Sunderland SR5 9QY should not be treated as the address of one single identifiable company.
Evidence shows that the address has been used as part of outsourced correspondence and response handling, with Paragon Customer Communications having a particularly strong documented connection.
Allianz Global Investors was still using the Sunderland PO Box through Paragon for shareholder correspondence in 2026, while historical Carling promotions demonstrate that RHU and the same address have also been used for promotional fulfilment.
Currys-related letters have been reported by recipients, but Currys currently publishes a different Care & Repair postal address, so the association should not be presented as proof that it presently operates PO Box 1408.
If you receive unexpected correspondence, identify the company named inside the letter and verify it independently before providing sensitive information or making a payment.
FAQs About PO Box 1408 Sunderland SR5 9QY

Is PO Box 1408 Connected To Currys?
Some recipients have reported Currys-related correspondence carrying the Sunderland address. However, Currys currently lists a different postal address for its Care & Repair service, so PO Box 1408 should not be described as Currys’ confirmed current postal address.
Is RHU Sunderland A Legitimate Sender?
RHU has appeared in legitimate historical promotional documentation using PO Box 1408, including official Carling promotion terms. The letters should still be assessed according to the organisation and purpose stated inside them.

Should I Respond To A Letter From PO Box 1408?

Find the company’s official contact details independently and ask whether it sent the letter. Do not provide passwords, PINs or unnecessary financial information during verification.
