Handling Craigslist phone verification without tying it to a personal mobile

Why does our Craigslist posting workflow keep stalling on a phone check?

Property managers, small recruiters and local service businesses often post on Craigslist from a shared company login. Sooner or later the site asks for a phone number, and whoever is at the keyboard types in their own mobile. Months later that person has moved on, the account is still bound to their number, and the next verification prompt goes to someone who no longer works there.

Agencies that manage listings for several clients see the same thing at scale, while QA teams building tools around classifieds need a repeatable way to see the prompt end to end. OTP Route gives each of those situations a number that belongs to the workflow, not to an individual, and a code that lands where the team can see it. The agencies page explains how client work is usually organised.

What does Craigslist use phone verification for?

Craigslist uses a phone check as an anti-abuse measure. It can appear when an account is created, when someone posts in certain categories or locations, or when the site wants to confirm the person behind a listing again. The prompt sends a short code by text that must be typed back before the action goes through.

The exact rules are Craigslist's to set and they change, so don't build a test that assumes the prompt will appear every time. Design it to handle both outcomes.

How do we receive a Craigslist OTP through the API?

Create a Bearer key in the Developer console (prefix or_live_) and call https://otproute.com/api/v1. The service id is craigslist.

1. Read the live price with GET /api/v1/prices?country=<id>&service=craigslist.
2. Order with POST /api/v1/activations and {"service": "craigslist", "country": "us"}, swapping in the country id you need.
3. Enter the returned number at the Craigslist prompt and choose the text-message option if a choice is offered.
4. Pick up the code when your listener gets activation.sms_received, or have a small script query GET /api/v1/activations/{id} until the status changes.
5. Cancel abandoned orders with POST /api/v1/activations/{id}/cancel.

For webhooks, validate X-OTPRoute-Signature by computing HMAC-SHA256 over the timestamp, a dot and the raw body with your endpoint secret; refuse stale timestamps. Write results keyed on the activation id so a repeated delivery is harmless. Polling suits a one-off script; webhooks suit anything that runs in parallel. Request details live in the docs.

Which country should a Craigslist phone number come from?

The craigslist route is available in 197 countries. Craigslist itself is most active in North America, so most teams choose the United States or Canada, but the list also covers the United Kingdom, Mexico, Australia, Philippines, Germany, Spain, India, Japan, Brazil, the Netherlands and many more.

Match the number to the market the account actually operates in. A Toronto rentals account verified with a number from another continent is a mismatch Craigslist may notice, and a test of your Canadian onboarding flow is only meaningful with a Canadian number. Browse every route from the countries page.

Can a non-technical team member get the code from the dashboard?

Yes. Sign in, open the OTP Gateway, pick Craigslist as the service and the country you need, and confirm the price shown. Copy the number into the Craigslist prompt, request the text, and the code appears on the activation card. Each number covers one verification.

Why did the Craigslist code not arrive?

Craigslist can be selective about the numbers it accepts and may decline virtual numbers outright. When that happens, the SMS is never sent and the activation simply expires.

• Leave the 20-minute window running. With no SMS, the full amount goes back to your wallet automatically.
• Try again later, or place a fresh order so a different number is used.
• Try another country only if it genuinely fits the account's market.
• Don't hammer the endpoint with back-to-back orders; space attempts out.

When re-verification is a regular event rather than a one-time step, a temporary number is the wrong tool.

When is a Dedicated Number better for a Craigslist account?

If the same business account must log in again next month, it needs a number that will still be yours. Dedicated Numbers fill that gap in the United States and Canada, from $1.95/month: inbound SMS shows in the dashboard and is forwarded to your webhook as number.sms_received, and you can also send texts and place calls from the browser. Each prepaid term renews out of your wallet balance, and you can let the Craigslist line go whenever it stops being useful. See virtual numbers for the details.

What counts as responsible Craigslist use?

Follow Craigslist's terms of use and posting rules. Keep to one account per real person or business, post genuine listings, and never use these numbers to multiply accounts or to get around a block. OTP Route is meant for testing your own products and operating your own legitimate accounts, and our Acceptable Use Policy applies. Craigslist is a trademark of its owner, and we have no affiliation with it.
