Check & restore
NIE check: validate, find and restore your number
Three problems, three tools: check whether a NIE is valid, find your own number on documents, and restore a lost one. Start with the tool — it is free and instant.
Tool
NIE validator
Check any NIE's format and control letter instantly — free, no signup.
Guide
Where is the NIE on documents?
Visa sticker (support number), TIE card, certificate, tax filings — document by document.
Guide
Lost or duplicate NIE
The number never changes. How to get a duplicate certificate — same number, new paper.
Guide
NIE validity & expiry
The number is for life. What actually expires — TIE, permit, visa — and what “renewal” really means.
