Quarterly 340B Program site registration is open April 1-15. Health centers will still be able to register a site that has been verified as implemented and with a site status reflected as “active” in HRSA’s Electronic Handbook Form 5B through Friday, May 22. After that date, the system will close to prepare for the July 1 start. Email the 340B call center or call 888-340-2787 (Monday-Friday, 9:00 am – 6:00 pm) to register a new site or ask questions. Centers will need to provide the following information: health center name, site/clinic name, site IDs for all sites, HRSA/BPHC grant number, contact name and email address and authorizing official name and email address. The authorizing official will receive an email message that the account is unlocked, and a registration may be submitted.
