How does a car salesman get a business phone number?
Short answer
You have five realistic options: use the store’s line, add a free Google Voice number, add a second SIM or eSIM to your phone, get a business line app like Quo, or use a car-sales app like Relay Solo that includes a number and AI replies. If you want customers to have one number that stays yours when you change stores, pick an app-based number you control, not one the store owns.
The options
| Option | Cost (USD) | Number stays yours if you change stores | Built for texting leads |
|---|---|---|---|
| The store’s line or CRM texting | Free to you | No, it belongs to the store | Yes, store-branded |
| Your personal cell | Your phone plan | Yes | No, and it puts your personal number everywhere |
| Google Voice | Free, or $10+ a user a month with Workspace | Yes | No. Its policy bars bulk commercial and automated messages |
| Second SIM or eSIM line | A second carrier plan | Yes | No follow-up or AI, and business texting rules still apply |
| Quo (formerly OpenPhone) | $15 to $47 a user a month | Yes, and you can port a number in | General business texting, not car-specific |
| Relay Solo | $49 or $89 a month + US$29 once | Yes, it belongs to your Relay account | Yes, with AI replies to car leads |
What matters for a car salesman
- Who owns the number. A store line stays with the store when you leave. A number on your own account stays with you.
- Whether you can text from it legally at volume. US carriers require business texters to register (A2P 10DLC). Unregistered business texting gets blocked.
- What happens when you are busy. A plain second line rings and waits. A car-sales app can answer the lead for you.
How setup works with Relay Solo
Pick an area code and your account is ready in minutes. Calls work right away. Texting turns on after carrier approval, typically 5 to 15 business days. The US$29 carrier registration fee is charged once, and your monthly plan starts only when texting is approved.
Common questions
Should a car salesman have a separate business number?
Most reps who build their own book use one, so their personal cell stays private and customers have a number that stays the same if they change stores.
Can I keep my business number if I leave the dealership?
Only if the number is on your own account. A store line or CRM number stays with the store. A Relay Solo number belongs to your Relay account.
Do I have to register a business number to text customers?
In the US, yes, if you text customers for business from a regular 10-digit number. Carriers call it A2P 10DLC registration. Relay files it for you.
