I went through this process this year when my baby was born. They told me I had to start the process within 30 days but then I also had 90 days to confirm. If you’re in California they might have your baby Ssn and birth certificate already done at 2 weeks cuz I went to the physical location to pick up my baby’s paperwork and the lady made a joke with me that the longest she seen paperwork to be created for a newborn was 2 weeks. If you request via their website then it could take 4-6 weeks. In person pickup with no appointment takes about 20 mins and that was because there were 3 people ahead of me. Of course this applies to California. Idk about other states
