postalref

Read a package barcode or tracking number (IMpb): its layout, each field's digits and meaning, whether the check digit holds, and the service type code's row in the USPS list, each with the passage that says so.

What USPS means by a name or abbreviation: each registry entry it names, in the order search ranks them, with its kind and tier, the USPS words that define it and the page they're on, its other names, postalref's own explanation where it has one, and postalref's page about it. An entry USPS ended says when, what replaced it, and USPS's words that say so; one renamed gives its former names, each with USPS's words.

What changed in a code table or document between two editions: each code added, removed or changed and each changed section, rated editorial, additive or breaking, with who rated it.

Look up a USPS code: its row as USPS prints it in the newest edition that lists it, the codes its cells name, the editions that list it and its history, each row with its passage id. A code is found without the marks USPS prints around it and in a row USPS prints for several codes: 750 finds *750, 858 finds 858 and the dropped 858**, and 13 finds PTR's row 01 / 13. Two digits are also tried as three: 55 finds PTR's 55, then STC's 055.

Read any document postalref holds page by page, as extracted, to quote it: a quote cites the revision's sha256, the PDF page and the words exactly. A text without pages, a web page or a product page, reads in parts, and a quote from one cites no page.

Search the codes, terms, banner texts, specs and documents postalref models, by one index: names and codes whose key is the query's first, then those that start with it, then those with words that start with its words, then codes whose row has its words. A term hit carries its kind (mail-class, extra-service, service, program, system, file, identifier, document, facility, container, role or term) and its tier (core, or reference: only in Publication 32, the glossary of July 2013, with that date). A query of 20 or more digits comes back as one to decode.

Search every document on PostalPro by title and file name, with its page and newest file, and the product pages and downloads postalref holds by title. Each one postalref holds the text of carries the id read_source reads it by.

Search the text of every document postalref holds for the pages that say the words, best first: those that say them as a phrase, then by how much of the page they are and how many of them it says side by side or close together, a table of contents last, and at most three pages a document. A page needn't have the words a question asks with, such as how, get or take. Each hit gives the id and page read_source reads, and the words around them. Use it when no title names what you're looking for, as for a price in the Mail Classification Schedule or a rule in a DMM chapter.
