What to do if…
you notice your passport is not signed and you are close to departure

Short answer

Sign it correctly now (if you are required to) — an unsigned UK passport is not valid for travel. Use a black ballpoint pen and sign only on the “holder’s signature” line.

Do not do these things

  • Do not travel to the airport assuming “it will be fine” — an unsigned passport can be treated as invalid.
  • Do not sign anywhere except the “holder’s signature” line, and do not sign below the line.
  • Do not use pencil, erasable ink, correction fluid/tape, or try to “fix” a mistake by crossing out and rewriting.
  • Do not let someone else sign for you (unless your passport explicitly says you’re not required to sign).
  • Do not panic-replace your passport unless there is an actual signing error or you are genuinely unable to sign.

What to do now

  1. Check if you actually need to sign.
    Look at the page with your photo and personal details. If you are 11 or under, or HM Passport Office has marked you as not required to sign due to disability, the passport should indicate this (for example, wording like “the holder is not required to sign”). If it says that, do not add a signature.

  2. If you are required to sign: sign it immediately, the correct way.

    • Use a black ballpoint pen.
    • Sign your usual signature (the one you use for official documents).
    • Sign on the “holder’s signature” line only and do not go below the line.
    • Let the ink dry fully before closing the passport.

  3. Double-check you signed the right thing in the right place.
    Confirm you signed your passport book (not a passport card or a photocopy) and that the signature is on the correct line on the passport’s signature page.

  4. If you are already en route or at the airport and don’t have a suitable pen:
    Get a black ballpoint from an airport shop, airline desk, hotel reception, or a travel companion, and sign it before you reach check-in/bag drop if possible.

  5. If you made a mistake signing (wrong name, scribble, went outside the line): stop and switch to “damage control.”
    Do not try to correct it. Treat this as time-critical: contact HM Passport Office for advice about what your options are based on your departure time (and be ready for the possibility you may need a replacement/urgent solution).

  6. Give yourself time buffer.
    Even if you’ve signed correctly, arrive earlier than you otherwise would. This buys time if check-in staff want to re-check the document.

What can wait

  • You do not need to research whether other travellers “got away with it.” Focus only on making your passport valid now.
  • You do not need to replace the passport if you signed correctly and you are required to sign.
  • You do not need to do anything else “extra” with HM Passport Office if the signature is now correct.

Important reassurance

This is a very fixable problem in most cases: if you’re required to sign, you can usually make the passport valid by signing it properly before you travel. The key is to do it calmly and correctly once — not to rush and create a signing mistake.

Scope note

These are first steps for the specific problem of an unsigned passport close to departure. If there are other issues (damage, name mismatch, expiry/validity rules for your destination), you may need separate, situation-specific guidance.
