Direct answer: report the new passport number and any changes to the authority indicated by the Questura; do not alter the permit yourself. Prepare old and new passports, permit, tax code and a written request. If the name is transliterated differently, request a formal correction and keep proof. Sources: competent Questura and Portale Immigrazione; checked 24/10/2026.
Who this applies to: Anyone with a new passport who must update the record linked to the permit, not confuse it with renewal.
Practical steps: 1) copy the new passport and keep the old one, the permit and receipt; 2) ask the Questura named on the permit whether an appointment or kit is required for the update; 3) submit the new document and evidence of the changed details without filing a renewal while the permit is still valid; 4) bring both passports and the receipt to the appointment.
Documents to keep: old and new passports, permit, identity page, tax code and appointment proof.
Verifiable timing and costs: The update follows Questura instructions and does not extend the permit’s validity.
Exceptions and special cases: If expiry is near, the office may ask for update and renewal together.
If the procedure stalls: Submit both passports and request proof; do not rely on the old passport alone for travel.
Practical example: After passport renewal, the applicant brings both passports and the permit to the Questura before travelling.
