An eCheck is a payment from a bank account that moves on the ACH Network rather than as a paper check. Nacha lists eCheck as another name for ACH payments, along with direct debit and EFT. The term often covers check conversion, where a business uses the routing, account and serial numbers from a paper check to start a one-time ACH debit. Regulation E treats that conversion as an electronic fund transfer. The business must give notice and get the consumer's authorization for each transfer. A check sent as an image through the check collection system is not an electronic fund transfer.
What is an eCheck?
"eCheck" is a common name for a payment drawn from a checking account and moved electronically. It isn't a separate payment network. Nacha says direct deposits and direct payments are "also known as direct debit, EFT, electronic bank transfer and eCheck," and that they move on the ACH Network. The ACH Network reaches all US bank and credit union accounts.
In practice the word is used two ways:
- A bank debit started online or by phone. The customer types in routing and account numbers instead of writing a check. This is an ACH debit.
- Check conversion. A business takes a paper check and uses the numbers printed on it to start an electronic transfer instead of depositing the paper.
Is an eCheck the same as ACH?
For most purposes, yes. Both describe a payment from a bank account that settles over the ACH Network under the Nacha Operating Rules. The same authorization, return and dispute rules apply as for any other ACH debit. "ACH" names the network. "eCheck" describes the payment from the customer's side.
What does Regulation E say about converting a check?
Regulation E, 12 CFR 1005.3(b)(2), covers a check, draft or similar paper item used as a source of information to start a one-time electronic fund transfer from a consumer's account. The rules are:
- Consent. The consumer must authorize the transfer.
- Notice. The business must give notice that the transaction will or may be processed as an electronic fund transfer, and get authorization for each transfer.
- How consent happens. The consumer authorizes the transfer when they receive the notice and go ahead with the payment.
- At the point of sale. The notice must be posted in a prominent and conspicuous place, and the consumer gets a copy at the time of the transaction.
The official interpretation adds that notice is generally needed for each converted check. When a customer mails a check to pay a bill, such as a utility bill, they must get notice for each payment the business plans to convert. A coupon book with set dates and amounts can carry one notice for all of them.
When is a check-based payment not an electronic transfer?
Regulation E's definition at 1005.3(b) excludes some payments that look electronic:
| Payment | Covered as an electronic fund transfer? |
|---|---|
| Check converted to a one-time ACH debit | Yes |
| Check sent as an electronic image through the check collection system | No |
| Returned check re-presented electronically | No, because it started as a check |
| A fee for a returned check collected by electronic debit | Yes, with the consumer's authorization |
What protections does a consumer get on an eCheck?
When an eCheck is an electronic fund transfer from a consumer account, Regulation E's error rules apply. A consumer has 60 days after the bank sends the statement showing the error to report it. The bank generally has 10 business days to investigate. On Stripe, a consumer can dispute an ACH debit for up to 60 calendar days, and a business account for two business days. See EFT payment for the wider definition.
