How to check old Premium Bonds
Last reviewed: July 2026
Short answer
Old Premium Bonds do not expire simply because the paperwork is old. If they have not been cashed in, NS&I says they remain valid and keep entering monthly draws. Use your holder's number to check prizes. If that number is missing, recover the record through NS&I first.
Start with what you still have
- Holder's number: use it in the official checker to see recent and unclaimed prizes.
- Old Bond record: it should show the holder's number and the Bonds linked to it.
- Only a name or old address: use NS&I's tracing or replacement-record process. Public prize checkers do not search personal holdings by name.
Historical numbers are not the same as your prize history
NS&I publishes downloadable winning Bond-number files for recent draws and an annual list of older unclaimed winning numbers. Those files can help with research, but a personal prize history still needs to be confirmed through NS&I. Our checker currently compares against the latest published draw only and should not be treated as a complete historical search.

- 1. Sign in to the NS&I online service if the holding is already registered.
- 2. Ask NS&I for a replacement Bond record if you know you hold Premium Bonds.
- 3. Use the NS&I Tracing Service if you are not certain whether you still have an account.
- 4. Once recovered, use the official checker for the current month, the six previous draws and unclaimed prizes.
