Apostille vs. Embassy legalisation for Iran
An apostille from the United Kingdom is not accepted for documents that are heading to Iran. Anyone searching for a Sunderland apostille for Iran needs the fuller route instead: a checked and endorsed paper followed by a second sign-off from Iran's own mission in London. The single stamp that satisfies most Hague destinations will not satisfy officials in Tehran, so going straight for an apostille wastes both the fee and the wait.
The practical difference is what happens once Milton Keynes has finished its part. For a Hague destination, that endorsement is the end of the process. For Iran, it is only the halfway point: the paper still has to travel on to Iran's mission for its own closing seal before an official there will treat it as genuine. That is what document legalisation for Iran means in practice, and it is why the plain apostille route stops short here.
Iran's Hague status & what it means
Iran does not currently accept the Hague apostille, which is why every document intended for Iran requires embassy legalisation instead of the single-stamp route. This is a statement about Iran's own rules, not about the United Kingdom's — the UK issues apostilles for the countries that do accept them, and treats Iran differently only because Iran asks for a different kind of certification.
No accession year is on record for Iran, so none is given here — the position is that an apostille is not accepted, not that membership is merely pending. A reader planning an apostille from United Kingdom to Iran should treat the embassy stage as mandatory, because Iran's own authorities decide whether a document is recognised, and they have not adopted the apostille for this purpose.
The Sunderland → Iran route step by step
The route begins with the FCDO Legalisation Office, PO Box 6255, Milton Keynes MK10 1XX, which authenticates the underlying UK document by post; there is no counter in Sunderland or anywhere else to visit in person. Once that authentication is complete, the paper is sent on to the Iranian embassy or consulate, which reviews the FCDO's work and adds its own legalisation stamp — the step that actually makes the document usable in Iran.
If the document is a birth, marriage or death certificate, Sunderland Registration Service, City Hall, Plater Way, Sunderland SR1 3AA, can issue a fresh certified copy to start this chain with, so the family's own original stays at home rather than travelling twice through the post. That copy goes through the same FCDO authentication and Iranian embassy legalisation as an original would, and it is accepted for the same purpose.
Cost & timing for this route
The FCDO stage costs £45 for the standard postal service, or £40 for registered businesses using the next-day route. A separate consular fee, set by the Iranian embassy or consulate rather than by the FCDO, applies for the legalisation stamp at the end of the chain, on top of the FCDO's own charge.
Standard turnaround through the FCDO is up to 25 working days, plus postage, with a next working day service available to registered businesses only. Because Iran's route adds the embassy stage after the FCDO has finished, the embassy's own processing time runs on top of that figure rather than inside it, so the full journey to Iran takes longer than the FCDO stage alone.
Destination-specific requirements
Iranian authorities are the body that ultimately decides whether a legalised document is accepted, and their requirement is the full embassy route described above rather than a single apostille stamp. A document sent to Iran without that final embassy stage is incomplete, no matter how correctly the FCDO authentication was carried out beforehand.
For academic, commercial or personal documents alike, the same order applies: FCDO authentication first, embassy legalisation second. There is no shortcut that skips the embassy stage for Iran, and no additional fee or date beyond the £45 (or £40 next-day) FCDO charge and the up to 25 working day standard turnaround is set out here for the embassy's own part of the process.
