Pennsylvania's largest markets for architectural services firms

Census published architecture firm counts for 16 metro or micropolitan areas that include part of Pennsylvania. The largest is Philadelphia, PA-NJ-DE-MD, with 416 establishments (a multi-state area; its count covers every state it spans). Single-state metro and micropolitan areas account for 42% of the statewide total; the rest are outside any published area or in areas Census suppressed.

Team sizes at architectural services firms in Pennsylvania

56.0% of Pennsylvania's architectural services firms with employees had fewer than five people in March 2023, compared with 63.6% nationally. 74.7% had fewer than ten. At that size the phone is shared, so routing (who rings, when, and what happens after hours) matters more than the number of desk phones.

What architectural services firms in Pennsylvania use the phone for

Architects coordinate clients, consultants, contractors and permitting offices across long projects. Calls need to reach the project lead, and summaries of decisions help keep teams aligned.

Calls an architecture firm in Pennsylvania might handle in a typical week include:

• A permitting office calls about a submission.
• The firm calls a client to review a design.
• An engineer calls about structural details.

Texting clients

Firms text meeting confirmations and site-visit times.

Texting from a local number in Pennsylvania requires carrier registration (10DLC), a one-time $49 fee on Callata.

Callata vs. per-seat pricing for architectural services firms in Pennsylvania

Architectural services firms in Pennsylvania average 9.9 employees, so the comparison uses a 10-person team. On a per-user plan that headcount sets the bill: $249.50 a month on Ooma Office Pro or $300.00 on RingCentral RingEX Core at list price (checked September 28, 2026). Callata comes to $199.00 a month for 10 users ($99 a month with 5 users included, then $20 per additional user), below both.

Over a year, that is $1,212 less than RingCentral for an architecture firm in Pennsylvania of that size. Annual contracts lower some competitors' prices, so compare the plan you would actually sign.
