document number on work authorization card
Incorrect Form Number: The Permanent Resident Card form number is âI-551â (âEye dash five five oneâ) and the Employment Authorization Document is âI-766.â In the example above, the number reads â1-551â (âOne dash five five oneâ). We have also seen âI-531,â âI-3-2-1,â âI-736â and others.
