Buy verified Chime Bank accounts do you mean officially verifying your account with Chime (identity verification, etc.), or “buying” someone else’s verified Chime account / using a third-party verified account? The answers are very different depending on what you meant.
Meanwhile, here are what I found about the benefits of having an officially verified Chime account (i.e. having completed Chime’s identity verification / KYC process)
Benefits of Buying a Verified Chime Accounts
Access to full features You’ll be able to use all of Chime’s core services: spending & savings accounts, direct deposit, mobile check deposit, etc.
Early direct deposit Verified account holders can often get paychecks deposited up to 2 days earlier than traditional banks.
Overdraft protection via SpotMe Chime offers a no-fee overdraft service (SpotMe) to eligible users (which usually requires being “verified” / having certain account activity) so you don’t incur overdraft fees.
Credit-builder tools Being verified may allow access to Chime’s Credit Builder products, helping build or improve credit without traditional credit checks.
Higher transaction / limit thresholds Verified accounts tend to have higher limits for transfers, deposits, withdrawals than unverified or partially verified ones.
Regulatory compliance / trust Verification helps with regulatory (e.g. anti-money laundering, fraud prevention) compliance. It also gives more trust from other institutions, merchants, employers, etc.
Security and protection Verifying your identity makes account takeover or misuse harder. Also, Chime accounts are FDIC insured (through their partner banks) for up to $250,000.
