These are equivalent to Class 1 NICs, though are not paid for. For the most part, however, an international health insurance policy will not cover an individual when they have returned to their home nation, making the investment practical only if the policyholder is planning to be overseas for an extended period of time. Those traveling abroad for shorter periods of time, may wish to purchase a travel medical policy which can provide assistance during emergency medical situations abroad. This is despite a clear claim on the back of the NI card, and a smaller claim on the front, that it is not proof of identity. On occasions, some people may have a 'temporary' NI number, which follows the format TN 01 23 45 F, where 'TN' stands for temporary number and is static and 'F' stands for female (or in the case of men 'M' for male), though the last letter may differ (even though it's not required), and the numbers in the mid-section are your date of birth
