01 Non-Affiliation and Trademark Declarations

This publication is neither authorized, sponsored, endorsed, nor operated by the United States Postal Service (USPS), United Parcel Service (UPS), Federal Express (FedEx), DHL Express, or any other commercial courier or international postal administration.
All trademarks, service marks, trade names, official forms, brand references, and logos referenced across this website (including USPS®, Priority Mail®, First-Class Package Service®, Media Mail®, Parcel Select®, and Certified Mail®) are the intellectual property of their respective owners.

02 Nature of Operational Guidance & No Carrier Representation
The materials, checklists, layout diagrams, dimensional calculators, barcode placement matrices, and shipping inspection notes published on this site are compiled for general educational guidance and operational preparation. While our technical team regularly audits carrier manuals and domestic mail standards, postal regulations, zone rate classifications, dimensional weight factors, and hazardous material constraints are subject to unilateral revisions by postal authorities and regulatory commissions.
Users are expressly advised that reviewing our checklists does not substitute for official parcel acceptance, counter inspection, automated mail verification, or official induction at an authorized carrier acceptance unit.
03 Independent Verification and User Responsibility
Every sender, logistics manager, fulfillment specialist, and warehouse operator maintains sole responsibility for:
- Verifying current carrier-specific parcel specifications, girth limits, and weight tolerances directly through official regulatory documentation prior to physical shipment handoff.
- Ensuring full compliance with federal, state, and local safety rules concerning restricted articles, lithium batteries, perishable goods, liquids, and dangerous goods.
- Confirming recipient delivery addresses via certified address standardization systems (such as CASS-certified software) before printing shipping barcodes.
- Ensuring adequate internal cushioning, carton crush resistance, and appropriate closure tape application per current industry drop-test standards.
04 Limitation of Liability
To the maximum extent permitted by applicable law, MailReadiness Fieldbook, its editorial authors, contributors, and operators disclaim all liability for any direct, indirect, incidental, consequential, or operational losses arising out of or in connection with the use of this website. This includes, without limitation: shipping surcharges, return-to-sender delays, postage adjustment assessments, package damages during transit, address validation inaccuracies, or carrier non-acceptance events.
All digital checklists, reference sheets, tables, and procedural notes are provided on an “as is” and “as available” basis without express or implied representation of commercial fitness for a particular parcel shipment.
05 Strict Policy on User Reviews, Comments & Public Posts
To preserve technical rigor, eliminate promotional noise, and protect operational integrity, MailReadiness Fieldbook maintains a strict site architecture policy:

06 External Documentation and Authoritative Sources
