Fixing that requires a fancier kind of validation that involves sending that address a message that includes a confirmation token meant to be entered on the same web page as was the address.Ĭonfirmation tokens are the only way to know you got the address of the person entering it. People sign others up to mailing lists this way all the time. It's also important to understand that validating it per the RFC tells you absolutely nothing about whether that address actually exists at the supplied domain, or whether the person entering the address is its true owner. However, if you are forced to use one of the many less powerful pattern-matching languages, then it’s best to use a real parser. Python and C# can do that too, but they use a different syntax from those first two. in PHP) can correctly parse RFC 5322 without a hitch. The more sophisticated patterns in Perl and PCRE (regex library used e.g. (Scrape the rendered version, not the markdown, for actual is diagram of finite state machine for above regexp which is more clear than regexp itself The rest of it appears to be consistent with the RFC 5322 grammar and passes several tests using grep -Po, including cases domain names, IP addresses, bad ones, and account names with and without quotes.Ĭorrecting the 00 bug in the IP pattern, we obtain a working and fairly fast regex. One RFC 5322 compliant regex can be found at the top of the page at but uses the IP address pattern that is floating around the internet with a bug that allows 00 for any of the unsigned byte decimal values in a dot-delimited address, which is illegal. RFC 5322 leads to a regex that can be understood if studied for a few minutes and is efficient enough for actual use. Fortunately, RFC 822 was superseded twice and the current specification for email addresses is RFC 5322. NOTE: You can also contact PayPal via phone at 40 (personal or guest account holders) or 88 (business account holders) to confirm your account and assist with any specific questions regarding transactions they've processed.The fully RFC 822 compliant regex is inefficient and obscure because of its length. Locate the email in your inbox, and reach out them in order to best resolve. PayPal normally sends a notification to the email address on your PayPal account if your account changes status or experiences an issue. NOTE: You can also contact PayPal via phone at 40 (personal or guest account holders) or 88 (business account holders) to confirm your account and assist with any specific questions regarding transactions they've processed. TIP: If you're unable to locate the email in your inbox, be sure to check your Junk/Spam folder as well. Refer to your inbox to locate the verification email PayPal sends post creating a merchant account you can confirm your merchant account using the link in that email. This is a standard process PayPal has in place after you sign up for a merchant account on their system. If the email address entered in the "Payments & Payouts" section of your event's "Manage" page is correct, you may still need to confirm the account. You can find it below the Eventbrite order number in your "Orders report". PRO TIP: The transaction number can help PayPal locate your order(s). If the "PayPal email" matches what is on record in PayPal's system for your merchant account, move to the next option. Then contact PayPal to have any funds associated with the incorrect email and merchant account routed to the correct PayPal email and merchant account. If the "PayPal email" you entered is incorrect or has a typo, write it down for reference, correct it and save your changes. Log in to your Eventbrite account and go to Payments & Payouts (on your event's Manage page). NOTE: If you receive a message that your PayPal account is invalid, limited, or restricted, reach out to them to ensure your account is able to send and receive funds on PayPal's system. This is because PayPal is unable to direct funds to the intended merchant account. TIP: It's important to verify/confirm your PayPal account after it's created-funds are returned to cardholders after a period of 30 days if the account remains unverified. Check the email address entered and feel free to reach out to PayPal directly if the email address appears to be correct and simply needs to be confirmed in their system. This is normally due to a typo in the email address entered in the Payments & Payouts section of your event's Manage page, but could be related to an unconfirmed PayPal account.
