Do not travel within 72 hours of submitting the passport update if you can avoid it. Some airline systems pull Home Office data with a lag, and a very recent update may not yet be visible to ground staff at check-in.
Why UKVI Needs to Know About Your Second Passport
UK Visas and Immigration ties your identity and any existing visa or permission to the specific passport number you used at the time of application. If you travel on a different passport, the eVisa or vignette linked to the old document will not be readable at the border. This is not a theoretical risk: e-Gates and manual officers check the document number against Home Office records, and a mismatch can result in refused boarding even if your permission to enter is valid.
Linking a New Passport Through the UKVI Online Service
Log into your UK Visas and Immigration online account at www.gov.uk/update-uk-visas-immigration-account-details. Select 'Update your details', then choose 'Add a new passport or travel document'. You will need the new passport's number, issue date, expiry date, and country of issue. Once submitted, the system links the new document to your existing permission, and from that point the eVisa is readable against both document numbers when verified through the UK Visas and Immigration app or at a border.
When You Have an Existing Visa Vignette or BRP
If your current permission is a physical vignette stuck in the old passport, or a Biometric Residence Permit, the process is slightly different. You do not need to transfer the vignette; the underlying permission exists digitally in the Home Office system. Adding the new passport through the online account is still required, and you should carry both the old and new passports when travelling until you have confirmation the update is processed. Processing typically takes two to three working days, though it can extend to five during peak periods.
Second Passports Issued by a Different Country
If the second passport is from a different nationality, not just a renewal of the same one, the same update process applies but you must declare both nationalities accurately. The Home Office requires disclosure of all citizenships held, and submitting incomplete information is treated as a deception issue under the Immigration Rules. If you acquired the second nationality through a citizenship by investment programme and want to understand how that fits into a broader residency or travel strategy, the Second Passport Application routes guide covers which programmes produce the most useful travel documents for this kind of multi-jurisdiction situation.
Common Errors That Cause Delays
The most frequent mistake is entering the passport number with spaces or formatting characters, the system expects the number exactly as printed, no spaces, no hyphens. A second common error is trying to update details while an in-progress application is pending decision, the system locks the profile during that window. If the update fails or the account shows an error, the alternative is to contact the UKVI Resolution Centre by telephone (+44 300 790 6268 from abroad) rather than resubmitting, since duplicate submissions can flag the profile for manual review.
After the Update Is Confirmed
Once UKVI confirms the new passport is linked, verify it yourself using the View and Prove service at www.gov.uk/view-prove-immigration-status before travelling. Share the code with any airline or employer requesting proof of right to work or travel, this is faster than waiting for them to attempt the check at check-in. Keep the old passport intact and with you, as some airlines still cross-check against the document originally used to book the ticket.
Things people ask first.
Can I add a second passport to UKVI if my visa is already expired?
No, the update function is only relevant if you hold a current, valid permission. If your leave has expired, you need a new application rather than a document update.
Does adding a second passport cancel or affect my existing UK visa?
No. Adding a passport is a document link, not a new application. Your existing permission remains unchanged in its validity, conditions, and expiry.
What if I can't log into my UKVI account to add the passport?
Use the account recovery process on the UKVI sign-in page first. If that fails, contact the Resolution Centre by phone. Do not create a second account, that creates a duplicate identity record and causes significant downstream problems.
Do I need to inform UKVI if I get a new passport from the same country, not a second nationality?
Yes. Even a renewal passport from the same country has a new document number, and the eVisa must be linked to that new number. The update process is identical to adding a foreign second passport.
How long does it take for the new passport to show as linked?
Usually two to three working days, occasionally up to five. You will receive a confirmation email when it is done, and you can verify it immediately through the View and Prove service.
Can a UK immigration lawyer or agent do this update on my behalf?
You can authorise a legal representative to access your UKVI account, but the update itself is straightforward enough that most people do it without professional help. Using a representative is reasonable if your account has complications from a previous application.
Managing multiple passports across multiple jurisdictions?
Linking a second passport to UKVI is a one-time admin task, but building a multi-passport, multi-residency structure that actually holds up requires a full strategy. The Offshore Playbook covers the real mechanics of second passport acquisition, jurisdictions worth holding, and how residency flags interact with each other.
