Member ID guidance
Read the prefix from the current card.
Do not infer a prefix from another member or an older card. Federal Employee Program IDs beginning with a single “R” follow a separate route.
Masked formats use L for a letter, N for a number, and ? for an unknown character. No member IDs are published.
