State by State Report for

Telephone Central Office Building Pictures

 

This is a State by State report of where things are at for picture collection at the Telephone Central Office Buildings website.

The Telephone Central Office Building Pictures website strives not only for listing as many central office buildings as possible, but also strives for quality. Since the site's inception in 2005, the goal is to post high quality pictures and to be as accurate as possible.

Since 2022, there has been a huge effort to go through the site as time permits to look at each Area Code and assess all the pictures in that area code. Many older and lower resolution pictures are now being replaced with higher quality and higher resolution pictures as we find them. Older pictures are still being preserved and are designated as "Photo 2" in many cases. We feel that pictures over 10 years old and of low resolution are usually in need of replacement, and we are doing that as we continue to update the site. (We are doing that even for photos we took - so it's not just you - it's for us too!) Thanks for your understanding!   (grin)

Overall for US/Canada

The site has been around since 2005 and during that time I've been working hard. But it seems that there is so much more to do. I took a hiatus from 2018 to 2020, and again from 2022 to 2023, hoping to find a new method for the site (WordPress). But that didn't happen and I decided to press on with the old format from so many years ago. In 2020 I started again and did some major fixing and remodeling, continuing into early 2021, and again in early 2023. COVID was good for something, right? (grin) Work continues into early 2024 on updates.

United States

Overall: Overall for the whole United States is in pretty good shape. All states have at least one central office photo, all Area Codes have a least one central office, and most have multiple photos. A number states are complete, but there are an equal number of states that are barely touched or haven't been touched in years. So in other words, lots of work (and rework) to do.

Alabama

All area codes in Alabama have been refreshed in the 2022-2024 timeframe and should be good for several years.

Alaska

Last refreshed in October 2023.

Arizona

Last refreshed in April 2021.

Arkansas

All area codes in Arkansas have been refreshed in the 2023-2024 timeframe.

California

The parts around San Diego are pretty much complete (mostly around 2007-2010 timeframe) and GSV refreshed as of May 2021. The rest of the state is in pretty good shape in urban areas, though rural areas need work. A lot of work was done on this state in 2020 and again in 2021. Area Code 661 was worked on in December 2023.

Colorado

Area Code 719 was worked on in October 2023. The rest of the state is due for a refresh.

Hawaii

Mostly complete as of 2020. Should be in good shape for a while.

Idaho

Listings for major cities completed in 2020. Needs to eventually go back and fill in small towns.

Illinois

Places like Chicago are in pretty good shape, but overall the state has a lot of holes that needs to be filled. Some Area Codes are good, some need work.

Indiana

Indiana was worked on in 2020 to hit major cities. Need to eventually go back and get small towns.

Iowa

Iowa was worked on in 2020 to hit major cities. Need to eventually go back and get small towns.

Kansas

As of March 2021, both Area Codes 316 and 913 are mostly complete. Area Codes 620 and 785 have major areas covered. Need to eventually go back and get small towns.

Kentucky

Kentucky was worked on in 2020 to hit major cities. Need to eventually go back and get small towns.

Louisiana

Originally the state was covered in great detail by the late Mark Cuccia circa 2005 and 2006 using an early generation low-resolution cell phone camera. I've been updating the entire state using GSV to update the pictures. That was complete in February 2023 with the completion of the redo of Area Code 337.

Maine

For the most part, Maine is complete as of 2017. Need to revisit in a few years to replace aging GSV photos.

Maryland

Extensive remodeling of both Area Code 301 and 410 pages took place in February 2021. For the most part Maryland is complete.

Massachusetts

For the most part, Massachusetts is complete as of 2017. Need to revisit in a few years to replace aging GSV photos.

Michigan

Area Codes 231, 248, 269, 313, and 810 are in good shape. The rest of the state needs work.

Minnesota

Metro Twin Cities (Minneapolis/St. Paul) is complete as of 2017, but the rest of the state needs work.

Mississippi

For the most part, this state is in good shape. Area Code 228 was worked on in January 2024, Area Code 601 in August 2023, and Area Code 662 in February 2021.

Missouri

All area codes have been refreshed in the 2023-2024 timeframe.

Montana

Montana was worked on in 2020 to hit major cities. Need to eventually go back and get small towns.

Nebraska

Nebraska was worked on in 2020 and again in 2023 to hit the major cities and later most of the county seats. Probably done for now.

Nevada

Nevada has some pictures from contributions and some from GSV. The older TCO pictures have been refreshed with new GSV ones in February 2021. However more work needs to be done to hit smaller towns.

New Hampshire

For the most part, New Hampshire is complete as of 2017. Need to revisit in a few years to replace aging GSV photos.

New Jersey

New Jersey is mostly complete. Area Code 856 with parts of 609 were taken over the course of several years, filled in with GSV pictures. For the most part this is complete as of 2020.

New Mexico

Pictures for New Mexico are mostly from volunteer contributors. Far from finished, but a good start. However, some pictures are approaching 10 years old and need to be refreshed.

New York

Downstate New York (NYC & Long Island) is mostly complete as of April 2021, but upstate is lacking. Area Code 607 was reworked in 2023. Need to go back and fill in the rural parts of New York state.

North Carolina

Area Codes 336, 704 and 910 were worked on in 2023. Area Code 252 was refreshed in early 2024. Work continues on the rest of the state.

North Dakota

This state is very difficult because it contains mostly small independents that have for the most part transitioned away from TDM switching to softswitches/packet switches. In doing so, they descoped their former remotes and removed their identity and their CLLI codes. So now all the prefixes are now listed under one switch and one CLLI code for an entire company. That reduces the number of actual central offices to list since they're no longer in official documentation. I did some research in February 2021 and the 701 page now reflects this, but it's still something I'd like to go back and work on at a later date.

Ohio

Ohio was worked on in 2020 to hit major cities. Need to eventually go back and get small towns.

Oklahoma

Area Codes 405 and 918 had significant rework in 2023. Area Code 580 was reworked in May 2024.

Oregon

Last major work was in February 2021. Still needs work to fill in a lot of gaps statewide.

Pennsylvania

Area Codes 717 and 724 had significant rework in 2023. Area Code 412 was redone in 2024.

Rhode Island

Mostly complete as of 2017. Need to revisit in a few years to replace aging GSV photos.

South Carolina

Extensively worked on in 2020. Area Code 803 mostly complete, 843 and 864 hit on major cities. For the most part in pretty good shape.

South Dakota

A combination of user contributions and from GSV, covering some of the high points. With the new consolidation system, about 1/3 of the COs are now accounted for.

Tennessee

Area Codes 731 and 901 were worked on in early 2024. Other area codes may need some work.

Texas

Some area codes are in good shape, some others need to be worked on.

Utah

About one-third came from volunteers, the other two-thirds from GSV. Mostly complete as of April 2021.

Virginia

Most of the state with the exception of Area Code 434 has been updated during 2023 and 2024.

Washington

A lot from volunteers, especially in Area Code 509, otherwise GSV photos. Good representation in most area codes now with GSV. Could use some work for rural areas.

West Virginia

West Virginia was worked on in 2017 to hit major cities. Need to eventually go back and get small towns

Wisconsin

Mostly from volunteer contributions. But some of these are over 10 years old and need to be refreshed.

We have representative photos for all three places from GSV.

Puerto Rico

GSV has been to PR and I have a few pictures from there.

US Virgin Islands

GSV has been to USVI and I have a few pictures from there.

Canada

Overall: Overall Canada needs a lot of help. But then again, a lot of central offices are well off the beaten path. So getting pictures from Canada will be difficult overall. I could use some volunteers!
