If you have received a letter showing PO Box 313, Leeds, LS11 1HQ, the address alone does not provide enough information to identify the sender with certainty.
Current official information does not clearly establish PO Box 313, Leeds, LS11 1HQ as NHS England’s public correspondence address or as the exclusive postal address of another named organisation.
This is particularly important because a very similar address is officially used for NHS supplier administration:
PO Box 312
Leeds
LS11 1HP
The difference is only one PO Box number and the final letter of the postcode.
NHS England’s current general correspondence address is different again and is listed in Redditch.
For that reason, anyone receiving correspondence from PO Box 313 should identify the organisation named inside the letter and verify it independently rather than assuming the sender from the Leeds PO Box alone.
What Is PO Box 313 Leeds LS11 1HQ?
PO Box 313, Leeds, LS11 1HQ is a postal correspondence address, not necessarily the physical office of the organisation using it.
PO Boxes are commonly used to:
- Receive high volumes of mail.
- Separate correspondence from a physical office.
- Process returned documents.
- Centralise administrative communications.
- Route letters to back-office teams.
Under Royal Mail’s PO Box service, mail can be held for collection or forwarded depending on the customer’s arrangement.
This means the postcode printed on a letter should not automatically be interpreted as the organisation’s headquarters or customer-facing location.

Who Uses PO Box 313 Leeds LS11 1HQ?
There is currently insufficient authoritative public information to identify one organisation as the exclusive user of PO Box 313, Leeds, LS11 1HQ.
Some references have associated the address with NHS-related administration, but the official records available for current NHS correspondence point to different addresses.
Therefore, it would be inaccurate to state that PO Box 313 definitely belongs to NHS England simply because it is located in Leeds or resembles another NHS postal address.
The most reliable clues are normally contained inside the correspondence itself, including:
- Organisation name.
- Department.
- Reference number.
- Account number.
- Subject of the letter.
- Telephone number.
- Website domain.
- Reason for contact.
The same principle applies when identifying unfamiliar addresses such as PO Box 5040 Swindon SN4 4AQ, where the complete correspondence is more informative than the PO Box alone.
Is PO Box 313 Leeds an NHS England Address?
Current official information does not verify PO Box 313, Leeds, LS11 1HQ as NHS England’s main public correspondence address.
The official NHS England contact information currently gives its public postal address as:
NHS England
PO Box 16738
Redditch
B97 9PT
There is, however, an officially documented NHS administrative address in Leeds that looks very similar to PO Box 313.
The current NHS supplier information lists:
PO Box 312
Leeds
LS11 1HP
for certain central supplier invoice-processing arrangements.
PO Box 312 and PO Box 313
The two should not be treated as interchangeable.
| Address being searched | Official NHS supplier address |
| PO Box 313 | PO Box 312 |
| Leeds | Leeds |
| LS11 1HQ | LS11 1HP |
This similarity is probably one reason why PO Box 313 is sometimes assumed to have an NHS connection.
However, an address being similar to an official NHS address is not sufficient evidence of ownership.
If a PO Box 313 letter claims to come from an NHS organisation, identify the specific NHS body named in the letter and contact that organisation through independently obtained contact details.
Why Might You Receive a Letter From PO Box 313 Leeds?
A PO Box can support many different types of administrative correspondence.
Depending on the organisation using it, a letter could potentially concern:
- Customer administration.
- Account information.
- Supplier paperwork.
- Returned documents.
- Payment correspondence.
- Requests for information.
- Service notifications.
- Previous enquiries.
- Business administration.
The exact purpose cannot be determined from PO Box 313 alone.
For example, an invoice-related letter should be checked differently from correspondence relating to healthcare, an account, debt or a commercial service.
This is also why unfamiliar addresses such as PO Box 4988 Swindon should be assessed using the contents of the letter rather than assumptions based purely on the postcode.
Is a Letter From PO Box 313 Leeds a Scam?
Not necessarily.
The use of a PO Box is not itself a scam warning sign. Banks, government bodies, healthcare organisations and private companies all use central mailing addresses.
However, a PO Box also does not prove that correspondence is genuine.
Scammers can reproduce:
- Real company names.
- Government department names.
- Logos.
- Postal addresses.
- Employee names.
- Reference formats.
- Professional letter designs.
For this reason, the sender’s identity should be verified separately when a letter asks for money, personal details or urgent action.
What Warning Signs Should You Look For?
Extra care is appropriate if the letter:
- Demands an unexpected payment.
- Threatens immediate legal action.
- Gives an unusually short deadline.
- Asks for banking passwords or PINs.
- Requests one-time security codes.
- Directs payment to unfamiliar bank details.
- Includes a QR code leading to an unknown domain.
- Uses an unusual payment method.
- Contains conflicting company names.
- Refers to an account you do not recognise.
- Asks you to keep the communication secret.
- Requests sensitive personal documents without a clear reason.
None of these automatically proves fraud, but several warning signs together should prompt independent verification.
The same process can be useful when investigating correspondence from addresses such as PO Box 6887 Coventry CV3 9SD.
How Should You Verify a Letter From PO Box 313 Leeds?
Do not start with the contact information printed in a suspicious letter.
Instead, first identify the organisation it claims to represent.
Then verify it independently.
Sender Verification
Check:
- The full organisation name.
- The department named.
- Any customer or account reference.
- The reason for the communication.
- Whether you have dealt with the organisation previously.
- Whether the letter matches earlier genuine correspondence.
Next, find the organisation’s genuine telephone number or website independently.
If it claims to come from a government department, NHS organisation, bank or regulated business, use its official public contact channel.
Do not rely solely on:
- The phone number printed in the letter.
- A QR code.
- An email address contained in the correspondence.
- A website address that looks similar to an official domain.
Payment Verification
If payment is requested, confirm:
- You recognise the underlying bill or account.
- The amount matches your records.
- The reference number is genuine.
- The receiving organisation confirms the request.
- Bank details have not unexpectedly changed.
A sensible rule is:
Verify the organisation first and deal with the request second.
| Situation | Recommended action |
| Organisation recognised | Compare with previous genuine correspondence |
| Unknown reference number | Contact the organisation independently |
| Unexpected payment | Do not pay until verified |
| Bank details changed | Confirm through an established contact |
| Personal documents requested | Verify why they are required |
| Urgent threat included | Verify promptly without allowing urgency to bypass checks |
| NHS claimed as sender | Contact the named NHS body independently |
Can Companies House Identify Who Owns the PO Box?
Not necessarily.
Companies House is useful if a letter identifies a particular limited company, because you can check details such as:
- Company name.
- Company number.
- Registered office.
- Company status.
- Directors.
However, a correspondence PO Box does not necessarily appear as the company’s registered office.
Businesses can use different addresses for:
- Registered office purposes.
- Trading premises.
- Customer correspondence.
- Returns.
- Complaints.
- Invoice processing.
Therefore, failing to find PO Box 313 Leeds LS11 1HQ as a registered office does not automatically mean that no legitimate organisation uses it.
This distinction is important when researching addresses such as PO Box 1642 Northampton, because a postal processing address and a legal registered office can be entirely different.
Can You Visit PO Box 313 Leeds in Person?
It should not be treated as a public walk-in address unless the organisation responsible specifically confirms otherwise.
A PO Box primarily exists to receive mail.
Letters may be:
- Collected.
- Forwarded.
- Digitally processed.
- Routed to another administrative location.
Therefore, LS11 1HQ should not automatically be treated as a customer-service office, NHS clinic or reception address.
If an in-person appointment is necessary, obtain the organisation’s actual visitor address independently.
What Should Businesses Do If the Address Appears on an Invoice Request?
Businesses should apply additional verification if PO Box 313 appears in correspondence requesting changes to invoicing or payments.
Invoice-redirection fraud can involve criminals impersonating genuine suppliers or organisations and asking businesses to change payment details.
Before acting, verify:
- Purchase order number.
- Organisation code.
- Supplier identity.
- Invoice destination.
- Bank details.
- Contract contact.
- Any requested payment change.
If the communication claims to relate to NHS supplier processing, compare it carefully against the current published NHS supplier instructions.
The officially documented central Leeds invoice-processing address is PO Box 312, Leeds, LS11 1HP, not PO Box 313.
Do not redirect supplier payments or confidential documents simply because a letter contains NHS branding.
Why Are PO Box Addresses Difficult to Trace?
A PO Box may be part of a wider mail-processing system rather than a clear public identifier for one organisation.
A communication can effectively pass through:
Organisation → mail-processing operation → PO Box → recipient
The organisation creating the letter may therefore operate somewhere completely different from the address printed on the envelope.
Large organisations may also use several PO Boxes for different functions, such as:
- Payments.
- Complaints.
- Returns.
- Customer service.
- Claims.
- Supplier invoices.
This is why reverse-searching a postal address does not always identify the responsible sender with certainty.
The same limitation applies to addresses such as PO Box 61278 London, where the postal address may represent only one stage of a wider correspondence process.
Is PO Box 313 Leeds LS11 1HQ Legitimate?
PO Box 313, Leeds, LS11 1HQ should be treated as a correspondence address whose exclusive current user cannot be confidently identified from official public information alone.
There is also no sufficient current official evidence to describe it as NHS England’s main address.
That does not make correspondence using the address automatically fraudulent.
Instead, legitimacy depends on who claims to have sent the letter and whether that claim can be independently confirmed.
If a letter requests money, account details or sensitive personal information, verify the named organisation through an independently sourced contact channel before responding.
The address can be one clue, but it should never be the only evidence used to decide whether a letter is genuine.
