A2P 10DLC for recruiting & staffing.

Recruiting and staffing firms hit 10DLC compliance the second they enable ATS-triggered candidate SMS. Bullhorn, Greenhouse, Lever, JobAdder, JobDiva — every modern ATS that fires a 'thanks for applying, here's the next step' SMS routes through A2P infrastructure. Most ATS platforms now require A2P 10DLC registration before they'll send US SMS at all. The brand registration ladder ($48+ vetting, $15-$17 per campaign, $50 T-Mobile activation) hits firms before they can run their first sourcing campaign.

Carrier filtering on recruiting SMS is real. T-Mobile and AT&T flag recruiting content patterns aggressively — high-volume sends to numbers the recipient never opted in to, generic 'we have an opportunity for you' messages, repeated touches. Cold candidate sourcing via SMS is one of the most filtered categories. Recruiters who used to run cold SMS sourcing in 2022-2023 have watched delivery rates collapse over the last 18 months as carrier filtering tightened.

Sole-proprietor recruiters and small staffing shops face the worst registration friction. The sole-prop brand registration tier ($4) limits you to one campaign and very low throughput. Standard brand registration ($48+) requires an EIN, a verifiable business address, and a website that matches your company name. Many independent recruiters hit registration rejection because of EIN-to-IRS-records mismatches or thin website presence.

iMessage flips the recruiting playbook for warm candidate touch. Once a candidate has opted in — applied to a job, replied to a prior message, agreed to be contacted — iMessage delivers at 35-45% reply rates versus 8-12% for SMS in the same context. The blue bubble plus a recruiter's real name and photo reads as personal. For staffing firms running urgent shift fills or contractor placements, iMessage with read receipts gives real engagement signal in minutes, not days.

35-45% reply rate on opted-in candidates

Compare to 8-12% for SMS in the same warm-candidate context. Blue bubble + recruiter name reads as a real human, not a placement-mill blast.

ATS-triggered iMessage

Wire Bullhorn, Greenhouse, Lever, JobAdder, or JobDiva to fire iMessage on stage change, interview booked, or offer extended. Same triggers, better channel.

Per-recruiter line, no per-recruiter registration

Each recruiter gets their own iMessage line tied to their identity. Onboard a new recruiter in a day instead of waiting on TCR campaign approval.

Shift-fill speed

Read receipts and delivery rates that don't drop in carrier filters mean staffing firms can confirm contractor availability in minutes, not hours.

Do recruiting and staffing firms need A2P 10DLC?

Yes. ATS-triggered SMS counts as A2P regardless of which platform sends it. Bullhorn, Greenhouse, Lever, JobAdder, JobDiva, Workable all require 10DLC for US SMS. Personal-line workarounds for recruiters don't scale — carrier flagging hits any number sending recruiting-pattern volume.

What does 10DLC cost a staffing firm with multiple recruiters?

Brand registration ($48+) is one-time per legal entity. Campaign registration ($15-$17) covers all recruiters under that campaign use case, but most firms register multiple campaigns (sourcing, scheduling, placement notifications) at $1.50-$10/mo each. A 10-recruiter firm typically pays $40-$200/mo recurring before per-message carrier surcharges.

Why is cold candidate sourcing via SMS not working anymore?

Carrier filtering on recruiting-pattern SMS tightened significantly in 2024-2025. T-Mobile in particular filters generic 'we have an opportunity' messages, high-volume sends to non-opted-in numbers, and repeated touches. Cold SMS sourcing delivery rates have collapsed below 50% across most major carriers. Email and LinkedIn outreach for cold sourcing, plus warm iMessage follow-up post-engagement, is the current pattern that works.

Is iMessage TCPA compliant for recruiting?

Yes when used on opted-in candidates — applied to a job, replied to a prior message, agreed to be contacted. Tuco AI is designed for TCPA-conscious messaging with consent tracking and automatic opt-out handling. Use iMessage for the warm candidate touch (post-application, post-screening, interview reminders); use email/LinkedIn for cold sourcing.

How fast can recruiters be sending iMessage?

1-3 days. Tuco wires into Bullhorn, Greenhouse, Lever, and most modern ATS platforms via webhook or Zapier in an afternoon. Compare to 2-4 weeks for 10DLC campaign registration before a single recruiting SMS can go out.
