Your Baby's Identity Documents: The Sequence

Part of the Learning Center · included with every paid plan

A newborn has no legal identity until paperwork creates one. Three documents do the work: a birth certificate, a Social Security number, and (if needed) a passport. They arrive in a fixed order because each one depends on the one before it. The birth certificate proves the child exists. The Social Security number connects the child to federal systems. The passport lets the child cross a border. Families who understand the chain, and start it at the hospital, move through the sequence in weeks. Families who miss the first window spend months circling back.

· The chain: why the order is fixed
· The birth certificate: the root document
