Status: Medical Student (Accepted) AMCAS states that it usually takes ~4-6 weeks for verification to go through, but looking at the verification trend right now here: http://forums.studentdoctor.net/threads/2014-2015-verification-thread.1076112/ I would say you're looking at 3-4 weeks from the time of submission.
All details of all above should match. The verification process take 1 week to 15 days and can take longer if PayPal is unable to validate the information provided by you or there is discrepancy in your account. Note: as per Paypal you cannot have multiple accounts. If in case they found it they would suspend both the account.
