The Postal Service™ is making it easier for business customers to induct Certificate of Mailing shipments.
As of March 16, 2016, business mailers will be able to download and complete LiveCycle-compatible versions of two Certificate of Mailing forms: PS Form 3606-D, Certificate of Bulk Mailing — Domestic, and PS Form 3665, Certificate of Mailing — Firm (Domestic).
The availability of easy-to-complete forms will reduce the time and money that business mailers spend filling out hard copies by hand and⁄or creating privately printed versions for Postal Service approval. Using these forms will ensure consistency and compliance to the Postal Service standards for Certificate of Mailing acceptance.
The new forms are available now at http:⁄⁄about.usps.com⁄forms⁄all-forms.htm.
