Incremental Authorization
An incremental authorization is an additional Authorization request submitted to extend or increase an existing authorization hold when the actual charges are expected to exceed the originally authorized amount. Rather than voiding the original authorization and starting fresh with a new larger amount, the merchant submits a supplemental authorization for the additional funds, incrementing the total reserved amount to cover the full anticipated charge.
Incremental authorization is supported under EMV Mastercard and Visa network rules for specific merchant categories, most prominently hospitality (hotels, resorts), car rentals, and cruise lines, industries where the final charge at checkout may significantly exceed the initial hold placed at check-in. A hotel might authorize $500 at check-in for an estimated two-night stay and then submit an incremental authorization for an additional $200 when the guest extends their stay or racks up room service charges.
The mechanics work as follows: the original authorization places a hold for the initial amount, with the original authorization code. The incremental authorization adds funds to the existing hold, referencing the original authorization. The total reserved amount is the sum of the original and all incremental authorizations. At checkout, the merchant captures the final amount, which should be within the total authorized range across all authorization requests.
Without incremental authorization, merchants in these categories would face an uncomfortable choice: authorize high enough to cover worst-case scenarios (holding significant funds against the cardholder's account unnecessarily) or authorize conservatively and risk being unable to capture the full amount if final charges exceed the hold.
Frequently Asked Questions
Which card networks and categories support incremental authorization?
Visa and Mastercard both support incremental authorization under their respective card acceptance guidelines for specific merchant category codes, primarily lodging (MCCs 7011, 7012, 3501-3999), car rental (MCCs 3351-3441, 7512), and cruise lines (MCCs 4411). Amex and Discover also support incremental authorizations under their network rules. Support outside these defined categories varies, merchants in non-standard categories should confirm network rule applicability and gateway support before relying on incremental authorization in their payment flows.
What happens if the final capture amount exceeds the total authorized across all incremental authorizations?
Capturing an amount above the total authorized, without a final incremental authorization to cover the excess, may result in the issuer declining the capture or flagging the merchant for rule violations. Card network rules specify tolerance levels, the percentage above the total authorization that a capture may exceed, and these tolerances vary by network and merchant category.
How does incremental authorization appear to the cardholder?
Each authorization (original and incremental) typically appears as a separate pending item on the cardholder's account statement during the hold period, they may see multiple holds for different amounts, which can be confusing. Hotels and car rental companies communicate this through their check-in processes, informing customers that an initial hold will be placed and may be adjusted during the stay. This transparency reduces dispute and inquiry volumes.
