Payment Processing

Washington Gas has updated its payment processing information in an effort to provide improved customer service. The following explanations will clarify for customers when a payment posts to an account.

Generally, a bill payment is posted to a customer's account on the business day it is received if: (1) the payment is received at the Washington Gas published payment  address, which is P.O. Box 37747, Philadelphia, PA 19101-5047, in time for same-day processing, and (2) the payment is accompanied by the Washington Gas bill payment remittance coupon.

It's important to remember that payment posting timelines vary by payment method. For the purpose of electronic payments and walk-in payments, a "business day" is defined as the 24-hour period ending at 3:00 p.m. on each Tuesday through Friday. The period between 3:01 p.m., Friday and 3:00 p.m., Monday is defined as the Monday business day.

Mailed-in Payments: For payments mailed to the utility's published mailing address as noted above, payment processing is batched into two groups: Standard mail payments and non-standard mail payments.

Standard mail payments are customer payments mailed to the utility's published address that include the utility bill payment remittance coupon and a check or money order payable to the utility. Standard mail payments received by 7:00 a.m. shall be posted to the customer's account on the day received. Those received after 7:00 a.m., will be credited as expeditiously as possible, and no later than the next business day after the payment is received.

Non-standard mail payments are customer payments mailed to the utility's published  address as noted above that require special handling. Examples include: payments with multiple checks, multiple coupons, checks without a coupon, or a single check with multiple coupons that do not balance to the amount of the check. Non-standard mail payments shall be posted to the customer's account no later than the second business day after the day the payment is received. This includes payments a customer may initiate electronically through their bank or an independent payment processor, who then remits a check to the utility.

NOTE: When you pay your Washington Gas bill by check, you authorize Washington Gas to clear it electronically. Your check is not returned, and your payment receipt and bank statement serve as proof of payment. To opt out of the check conversion program, please call 1-888-862-4422.then option 1. Have your 10-digit Washington Gas account number available.

Payments delivered to other company offices, or payments without adequate information to identify the account to which the payment belongs, will be credited to the customer's account as expeditiously as possible.

Electronic Payments: Payments received through electronic banking file transmissions, through the automated payment program, or through the Washington Gas Web site or telephone or billing systems, will be credited on the same business day as the payment file is received.

In-person Payments: Payments received by the utility at its walk-in offices on any business day will be credited no later than the next business day. Payments delivered to unattended drop boxes before 8:00 a.m. will be credited as expeditiously as possible, and no later than the second business day after drop-off.
