Premium Bonds Checker by Name – Free Ways to Find Lost Prizes

Many people searching for a “Premium Bonds checker by name” expect a simple tool where they type a name and see results instantly. The reality is different: NS&I, the government-backed body that runs Premium Bonds, does not offer a public name-based search due to data protection rules. However, there are several free and official ways to check prizes, trace lost bonds from as far back as 1959, and find unclaimed winnings — even without a holder’s number. This guide explains exactly what works, what does not, and how to proceed step by step.

As of late 2025, approximately £106 million in Premium Bond prizes remain unclaimed across more than 2.6 million individual awards, according to NS&I data. Some of these date back to the first draws in 1957. Because Premium Bonds never expire, every prize from every draw since the scheme began is still payable. The challenge for many holders is locating their bonds or proving ownership without the original paperwork.

This article covers the official NS&I prize checker, the free tracing service via GOV.UK’s My Lost Account portal, how to handle bonds from the 1950s to 1970s, and what to do if you only have a name and an old address. All methods described are free and run by NS&I or its authorised partners.

How to Check Premium Bonds by Name: Free Methods in 2025

The short answer is that you cannot check Premium Bonds by name alone on the NS&I website or app. You need a holder’s number (9–10 digits, sometimes 8 digits plus a letter) or an NS&I number (11 digits) to use the instant prize checker. However, if you have lost that number, there is a free workaround: the My Lost Account service, which lets you search using your name, previous addresses, and approximate purchase details.

Key Facts About Premium Bonds Checking

How to Check if You Have Won a Prize This Month

Checking for recent wins is straightforward if you have your holder’s number or NS&I number. The quickest method is the official NS&I prize checker app, available free on iOS and Android. You enter your 11-digit NS&I number and the app shows the last six draws plus all unclaimed prizes going back years. The same information is available by logging into your account on the NS&I website.

Using the NS&I Prize Checker App

The app is available on the App Store and Google Play. After downloading, you enter your NS&I number (found on most letters and statements). No holder’s number is needed for the app — the 11-digit NS&I number is sufficient. The app displays all unclaimed prizes attached to your account, including wins from decades ago. NS&I also contacts winners by text, email, or post, but if your contact details are out of date, you may not receive notifications.

Checking Without a Number

If you cannot find your holder’s number or NS&I number, you cannot use the instant checker. However, you can call NS&I free on 08085 007 007 and provide your name and address details. They can verify your identity and tell you about any unclaimed prizes. Alternatively, you can write to NS&I at Sunderland SR43 2SB with your name, addresses, and signature to request a full prize list.

How to Trace Lost or Unclaimed Premium Bonds from the 1950s, 60s, and 70s

Bonds purchased before the 1990s may not have a modern holder’s number on record, and many were issued as paper certificates. If you have old Premium Bonds from 1959, 1970, or any era, they remain fully eligible for every monthly draw. Tracing them is free but requires a different approach than the instant online checker.

Using the My Lost Account Service

The GOV.UK My Lost Account service is a partnership between UK Finance and the Building Societies Association. You enter your name, address history, the approximate year of purchase, and an estimated value. The system searches NS&I records as well as banks and building societies for accounts that have not been touched in 15 years or more. No holder’s number is needed. This is the closest you can get to a “check by name” service.

Contacting NS&I Directly for Old Bonds

NS&I also offers a dedicated tracing form. You can download it from the NS&I help page for tracking lost investments. You will need to provide your current and previous names, addresses, the bond issue date (if known), and the approximate amount. Post the completed form to NS&I, Sunderland SR43 2SB. NS&I staff search their records and respond by post. The same process applies for bonds bought in the 1970s — include any serial numbers you have, although they are not strictly required because bonds are grouped under the holder’s name.

Serial Numbers and Old Bonds

Individual bond serial numbers are not needed for the tracing process. NS&I groups all bonds under a holder’s number. However, if you have paper certificates with serial numbers, include them as they can help verify ownership. For bonds issued before 1974, some fixed-value prizes (like £250) are no longer winnable in the draw, but if they were won at the time and never claimed, they are still payable.

How Far Back Do Unclaimed Premium Bonds Go?

Premium Bonds were first issued in 1956, and the first prize draw took place in 1957. The earliest known unclaimed prize is a £25 win from November 1957, belonging to a holder in South Yorkshire. Bonds from 1959 — the year many people search for — are still active and continue to be entered into every monthly draw. There is no statute of limitations on Premium Bond prizes.

1. 1957 — First Premium Bond prize draw. Earliest known unclaimed prize (£25) from November 1957.
2. 1959 — Bonds from this year are still valid. Many unclaimed prizes from this era exist.
3. 1970s — Bonds from this decade remain eligible. No online records exist without tracing.
4. 1990s — Introduction of the holder’s number system. Online checking becomes possible for newer bonds.
5. 2021 — NS&I launches the official prize checker app for iOS and Android.
6. 2025 — Current system: name-based checking not available; holder’s number required for instant results. ~£106 million still unclaimed.

What You Can and Cannot Do: Certainty vs. Uncertainty

Many online searches for “Premium Bonds checker by name” reflect a genuine need, but the capabilities of the official system are often misunderstood. The table below separates what is certain from what remains unclear or unavailable.

Why ‘Checking by Name’ Is Misleading

The idea of a name-based checker is understandable. Many people inherit paper bonds, find old certificates in a family home, or recall that a relative mentioned having Premium Bonds decades ago. Without a holder’s number, the natural instinct is to search by name. NS&I does not offer this because of security and data protection regulations: a public name search would expose personal financial information to anyone who typed in a name and address.

The closest alternative is the My Lost Account tracing service, which uses name and address history to locate bonds. This is a secure, one-to-one verification process rather than a public directory. For instant prize checking, the holder’s number is mandatory. Understanding this distinction saves time and prevents users from being misled by unofficial third-party sites that claim to offer name-based checks — none of which are legitimate.

Where Can I Find Official Information About Premium Bonds?

NS&I is the sole authoritative source for all Premium Bonds services. The NS&I help page for checking unclaimed prizes explains the full process. Reputable financial sites such as MoneySavingExpert, MoneyWeek, and Moneyfactscompare provide complementary guidance but always direct users back to official NS&I tools. No third-party app or website can legally or accurately check prizes by name.

What Should I Do Next to Check My Premium Bonds?
