Packaging Tips from USPS for Legal Documents
Secure packaging is key to protecting legal and business documents in transit. Follow these tips to ensure safe delivery:
- Use Flat Rate or Document Envelopes:
USPS offers Flat Rate Envelopes, including Legal Flat Rate Envelopes, which are ideal for letter-size and legal-size documents. They provide consistent pricing and sturdy protection.
- Avoid Folding Important Documents:
To maintain document integrity, avoid folding contracts, certificates, or notarized forms. Use rigid mailers or reinforced envelopes that keep contents flat and secure.
- Seal Securely:
Make sure envelopes are tightly sealed using strong adhesive flaps or packing tape. This prevents tampering and protects against environmental damage.
- Label Clearly and Correctly:
Print or write addresses clearly. Use USPS-approved labels and include a return address. If required, add Certified Mail® or signature confirmation stickers.
- Add Extra Protection if Needed:
For high-value or multi-page documents, insert them in plastic sleeves or folders before placing them in the envelope. This helps resist moisture and tearing.
- Choose the Right Envelope Size:
Legal Flat Rate Envelopes are designed to accommodate longer legal documents without bending. Don’t overfill, as bulging envelopes may not be processed correctly.
For shipping supplies, USPS offers free Priority Mail and Priority Mail Express envelopes, available online and at your local post office.
