Premium bonds: How winners can check on their prize for February’s results | Personal Finance | Finance

The first level uses a Royal Mail Postcode Address File (PAF) town. The next focuses on County or Local Authority. Level three focuses on Government Standard Region and the final level is by country.

This trickiness with location can all be avoided however by just entering the holder’s number for exact information. For February, there has been nearly 3.5 million prizes total and the winners will be notified via their registered addresses.

There is also an ongoing record of all unclaimed prizes dating back to June 1957. They categorise any prize that remains uncashed for 18 months as unclaimed.

It would be worthwhile for bondholders to hunt down the details for any numbers they may own. As it stands, there are 1,667,922 prizes worth £63,507,550 won 18 months or more ago and 624 prizes worth £27,600 won 18 months or more ago by bondholders whose names are unknown. Even the oldest premium bonds can still be winners as they do not expire.
