Reference excerpt

The Number Portability Administration Center (NPAC) is a function of the Federal Communications Commission (FCC) in the United States. It administers the routing of telephone calls and text messages (SMS) for the telecommunications industry and its customers in the regions of the North American Numbering Plan. As such, it facilitates local number portability in the United States and Canada.

History The Telecommunications Act of 1996 (47 U.S.C. § 251(b)(2)) established that all local exchange carriers must implement local number portability (LNP) in accordance with the regulations of the Federal Communications Commission (FCC). Subsequently, the FCC selected Lockheed Martin as the LNP administrator. The Number Portability Administration Center was originally implemented by the Communications Industry Services (CIS) division of Lockheed Martin in 1997. In 1998, Lockheed Martin formed a separate company, Neustar, for the management of the NPAC. At the time the work constituted the first database and registry to enable local number portability for the United States and Canada. The database contains the data for routing, rating, and billing telephone calls to telephone numbers that are no longer assigned to the telecommunication carrier that originally received the central office prefix or thousands-block allocation. On March 26, 2015, the FCC approved the recommendation of the North American Numbering Council (NANC) to award the contract to Telcordia Technologies, doing business as iconectiv, as the next Local Number Portability Administrator (LNPA), after 18 years of management by Neustar. The reasons for the change were cited as cost savings. With commission oversight, North American Portability Management, LLC (NAPM) negotiated the terms of a Master service agreement (MSA) with iconectiv. The MSA was submitted to the FCC for review and approval in March 2016. The iconectiv contract was finalized in August 2016. iconectiv officially became the administrator of the NPAC on May 25, 2018.

Worked examples

Example 1 — a first encounter with Number Portability Administration Center

Start with the simplest possible case. Write down what Number Portability Administration Center claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Number Portability Administration Center before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Number Portability Administration Center ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Number Portability Administration Center

In research: Number Portability Administration Center appears in mathematics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Number Portability Administration Center in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Number Portability Administration Center is common in secondary-school and first-year university syllabi. It links to neighbouring topics North American Numbering Plan, Telephone numbers, so understanding it makes those chapters shorter.
In everyday life: Look for Number Portability Administration Center outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
