Legally speaking, only account holders can "add-a-line" on Sprint(or Verizon or ATT for that matter). To simply process an upgrade on an
existing line, you need to be/have the following.
- You are added to the account as an Authorized User(meaning the account holder calls and asks Sprint to
add your Name to the account as an authorized user)
- You must know the 6-10 digit account pin
OR secret question
OR both social security number
of account holder and account address.
- Always have
your valid state or government issued Identification card with you when administering
any cellular account in a physical store.
Once again, authorized users cannot add or remove lines, but they can process upgrades and change features on existing lines.
This is not to say that all wireless sales personnel follow or want to follow the rules.
Cannot wait to pick up a GNEX on SUNDAY!
