What experts liked
My elderly mother refused to use the cordless phone extension and wanted a "real" phone. This 50 foot extension cord allowed us to "move" the hard-wired phone from the den to the living room so we didn't have to have another phone jack installed. Mom now has easy access to "real" phones without walking too far. Mom is a happy camper. Unbelievable low price. Thank you.

An Overview On Telephone Extension Cords

Smartphones might be an ever-present weight in our pockets, but landline phones are still a fixture at the office and even in many homes. And just like any piece of technology these days, these phones are increasingly connected to other devices — and that means extra connection cords.

Just because it’s called a landline phone doesn’t mean it needs to be landlocked to the wall that has the phone jack. A good telephone extension cord can give you greater freedom to move your desk or attach that phone to modems, fax machines or other office essentials.

One good thing about landline phones: The accessories and connection cord standards for them have remained much the same for decades, while charging cables and operating systems for smartphones seem to go obsolete every five years or so. If you need an extension cable for any standard telephone, look for the flat cord and squarish connections of an RJ-11 or RJ-12 cable.

Of the two, RJ-11 is the most common, and the oldest. They can be used to connect your telephone to a phone jack in the wall, or that phone to a modem or fax.

RJ-12 cords look the same on the surface, but check the ends and you’ll see six metal contacts occupying each of the six connection points. RJ-11 cords, by contrast, have four contacts. The extra contacts in the RJ-12 cords allow for additional phone lines, so they can be used by keyed telephone systems or office-wide PBX (Public Branch Exchange) phone systems. They’ll still work in older RJ-11 slots, but RJ-11 cords will not work in phones jack designated for use with RJ-12. This type is far less common, so if you’re buying for a home phone or simple office landline, RJ-11 cords should be all you need.

DYWM Fun Fact

The oldest continuously assigned phone number in the world is also a familiar one. According to New York City’s famous Hotel Pennsylvania, their number of 212-736-5000 was assigned in the 1930’s. Back then, it was listed as PE6-5000 — or in the shorthand that inspired a hit Glenn Miller tune, “Pennsylvania 6-5000.” That number still rings the front desk today, where you can hear the song if you’re on hold.

The Telephone Extension Cord Buying Guide

It should be easy to tell them apart, but don’t buy handset cord when you need an extension cord for your phone line. If you’re buying online, check the RJ (Registered Jack) number. Phone line that runs from your telephone to a phone jack or modem will be RJ-11 (or less commonly, RJ-12). Handset cord is the cord that connects your handset to the actual phone base, and that will be rated RJ-9 or 22. It will also be coiled in that telltale spiral, making it easy to spot in hardware store aisles.
