When you see PAI on a bank statement, it means the cash withdrawal was processed by Payment Alliance International, one of the largest independent ATM networks in the country. PAI operates or processes transactions for thousands of privately owned machines in convenience stores, gas stations, bars, and restaurants. Because PAI handles the data exchange between the ATM and your bank, its name appears on your statement instead of the shop where the machine actually sits.
Why the Entry Usually Reads “PAI ISO”
The full descriptor is typically “PAI ISO.” ISO stands for Independent Sales Organization, a third-party company authorized to process ATM or card transactions on behalf of a payment network. When you pull cash from a non-bank ATM, the machine’s transaction data routes through PAI’s system before reaching your bank. Your bank logs the processor’s name because that is the entity it actually communicated with.
The dollar amount you see usually combines two things: the cash you requested and the ATM operator’s surcharge. Some banks split these into separate line items; others roll them into a single withdrawal. Your own bank may also add an out-of-network fee, which shows up as its own charge. Federal law requires the ATM to disclose any surcharge on-screen or in print before you commit, and you have to actively continue past that notice, so a fee you were never shown a chance to decline is a legitimate basis for a dispute.
How to Identify the Specific ATM
Three pieces of information from your statement will tell you where the withdrawal happened. The transaction date shows when the machine communicated with your bank. The total amount confirms whether a surcharge was tacked on. Most important is the terminal ID, a string of roughly six to ten letters and numbers printed next to the PAI descriptor. That code identifies one specific ATM.
On most online banking portals, the terminal ID sits right after the merchant name in the transaction details. If your statement doesn’t display it clearly, your bank’s customer service line can usually pull it from the raw transaction data. Without that code, neither your bank nor PAI can pinpoint which machine ran the transaction.
Confirming Whether the Charge Is Yours
PAI maintains a location tool on its website at gopai.com that can map a terminal ID to a physical address. You can also ask your bank to look up the merchant location tied to the terminal code. Either route gets you the street address where the machine is installed.
If the address matches a store you visited that day, the charge is almost certainly your own withdrawal that you forgot about. If it points to a city or neighborhood you have never been to, that is a strong signal the transaction was unauthorized. Check the address against your calendar, receipts, or phone location history before deciding whether to file a dispute.
Your Liability for an Unauthorized Withdrawal
How much you owe after someone uses your card at a PAI ATM depends almost entirely on how fast you report it. Federal law sets three tiers, and the clock starts when you discover the card is lost or the account is compromised.
- Report within 2 business days, and your liability is capped at $50 or the total unauthorized amount, whichever is less.
- Report after 2 business days but within 60 days of your statement, and the cap rises to $500 or the unauthorized amount, whichever is less. This covers both the first $50 tier and any additional unauthorized withdrawals that occurred between day two and the date you reported.
- Report after 60 days, and you become liable for every unauthorized withdrawal that occurs after the 60-day window closes. There is no cap on that later loss. Anything that happened during the first 60 days remains subject to the limits above.
The third tier is where people lose real money. If someone drains an account over several weeks and no one notices, the losses after day 60 are yours to absorb.
How to Dispute a PAI Charge
Once you have confirmed the withdrawal isn’t yours, contact your bank’s fraud department. You can report by phone or in writing. The bank must accept an oral report, though it may ask you to follow up in writing within 10 business days. The federal deadline to report is 60 days from the date your bank sent or made available the statement showing the unauthorized transaction.
After you report, the bank has 10 business days to investigate and tell you what it found. It can extend that to 45 days, but only if it provisionally credits your account within the initial 10 business days. The bank may hold back up to $50 from that provisional credit if it has reason to believe the transfer was unauthorized. The 45-day window stretches to 90 days when the transfer originated outside the United States, involved a point-of-sale debit card transaction, or hit a new account within 30 days of the first deposit.
You get full access to the provisionally credited funds during the extended investigation. If the bank ultimately determines no error occurred, it can reverse the credit, but it must notify you in writing at least three business days beforehand and explain its reasoning. You can then request copies of the documents it relied on.
If You Miss the 60-Day Deadline
Missing the 60-day window doesn’t mean your bank will refuse to investigate, but it does mean you lose the federal protections that cap your losses. Under Regulation E, your bank has no obligation to cover unauthorized withdrawals that occur after the 60-day period ends if it can show those transfers wouldn’t have happened had you reported sooner. Some banks voluntarily extend zero-liability policies beyond the federal minimum, but that is a courtesy, not a legal requirement. Review your statements every month; a PAI charge that looks unfamiliar in January becomes much harder to resolve in April.
