Acceptable Use Policy

You must comply with applicable law and current USPS requirements for addressing, packaging, postage, hazardous materials, restricted items, prohibited items, and any other mailing condition that applies to your shipment.

Do not use TrackALetter to mail illegal, dangerous, explosive, flammable, toxic, controlled, counterfeit, stolen, fraudulent, or otherwise prohibited contents. Restricted materials may be mailed only when you independently satisfy every applicable rule.

You are responsible for determining whether an item is mailable and for obtaining and accurately completing any required packaging, markings, labels, declarations, permits, certifications, or other documentation. TrackALetter does not determine whether an item is lawful or eligible to mail.

Review the official USPS shipping restrictions before mailing prohibited, restricted, hazardous, or regulated contents.

You must accurately identify whether an item is a Letter, Flat, or Package and provide truthful addresses, contents, weight, dimensions, packaging, and service information. Do not misclassify a mailpiece or omit information to obtain a lower price or avoid a restriction.

Do not create, alter, copy, reuse, counterfeit, manipulate, or attempt to obtain postage or labels fraudulently. Do not intentionally create duplicate transactions, evade postage, interfere with barcode data, or exploit refund or adjustment processes.

Do not use stolen or unauthorized payment methods, dispute valid charges fraudulently, evade service fees, manipulate Balance or auto-refill, abuse promotional credits, or attempt to obtain duplicate credits, refunds, or value.

Do not sell, rent, transfer, share, or resell accounts or service access. Do not access another person's account, settings, addresses, labels, PDFs, shipment history, tracking details, payments, refunds, provider records, or administrative data.

Do not scrape, crawl, harvest, probe, reverse engineer, overload, disrupt, bypass rate limits, defeat security controls, automate abusive requests, or attempt to obtain private source code, credentials, tokens, webhook data, label files, or provider information.

Do not collect, disclose, sell, misuse, or repurpose another person's shipping, tracking, account, payment, or support data. Do not resell TrackALetter, provide unauthorized third-party access, or represent that you operate TrackALetter without written permission.

TrackALetter may investigate suspected abuse; restrict, suspend, or terminate an account; refuse or cancel a transaction; preserve relevant records; and take other reasonable protective action. TrackALetter may report suspected fraud or unlawful activity and may cooperate with payment, mailing, infrastructure, or law-enforcement authorities where required or permitted by law.
