A dedicated number for your company's alert texts

A dedicated number for alert texts is a toll-free number only your company uses. Every alarm arrives from one number your staff know on sight. No other sender can get it filtered. Staff let it through at night, and they can text it first to reach your team by email.

What changes with a dedicated alert number?

All Welco alerts go out from verified toll-free numbers that are never shared with marketing senders. A dedicated number is an add-on to the standard Welco features.

On a shared alerts-only number

  • Other alert senders use the same number as your alarms.
  • If one of them sends something that looks like spam, the number can be filtered for a while, and every account on it feels that.
  • Staff can reply to an alert, but they can't start a conversation.
  • Your alarms may sit in a thread alongside texts from other senders.

On your own dedicated number

  • Networks judge the number by your alerts only, and only systems you approve can send them.
  • Staff can text the number first, and their message reaches your team as email.
  • One contact to save, so people can let it through their phone's quiet hours.
  • Any blocked text still shows up in your plain-English delivery feed.

A real example: a tower site on its own line

A radio group texts tower alarms to two engineers. They moved to a dedicated number so their alarm line would never be touched by another sender's problems.

Alert email from towermon@broadcast.example.com, subject “Tower monitoring Tower 3 Alarm”. Welco trims it to one text of 77 characters: “Welco: [Tower 3] Alarm on zone 2: power at 11:48 PM. Reply STOP to opt out.”

Text received: Welco: [Tower 3] Alarm on zone 2: power at 11:48 PM. Reply STOP to opt out.

Both engineers saved the number as Tower Alarms and let it through at night. The broadcast radio and TV page covers transmitter and off-air alarms.

When a dedicated number makes sense

Many teams do fine on a shared number. A dedicated one earns its place in these cases.

  • Reports from the field

    Staff should be able to text the alert number first, for example to report a problem they found on site.

  • Alarms you can't risk

    Your alerts matter enough that you don't want another sender on the same number.

  • Many phones to set up

    Dozens of people need to save one number and allow it through Do Not Disturb.

  • Many sites, one thread

    Daily alerts from several sites should all land in a single conversation on each phone.

How to get a dedicated number

Dedicated numbers are an add-on for US and Canada accounts.

  1. Sign up and verify your business

    Every account goes through a short business check before it can send any alerts.

  2. Ask us to add a dedicated number

    Tell us you'd like one. The pricing page lists plans and add-ons.

  3. Tell your staff the new number

    Ask everyone to save it as your alarm line. Replies to it come back by email, just like before.

Frequently asked questions

Is a dedicated alert number a local number?

No. Welco sends alerts from verified toll-free numbers, and a dedicated number is a toll-free number only your company uses. Local and 10DLC numbers aren't offered for alerts. Here's what a toll-free number is.

Do I need a dedicated number to get replies?

No. Replies to alert texts reach email on shared numbers too. You need a dedicated number when people should be able to text your number first, without replying to an alert.

Can I get a dedicated number outside the US and Canada?

Not today. Dedicated numbers are for US and Canada accounts. Alerts on shared numbers also reach mobiles in the UK and the Netherlands. Other countries are in early access.

Does a dedicated alert number cost extra?

Yes. It's an add-on on top of your plan, and the pricing page shows the current price. Texts sent from it use message credits by the same rules as on a shared number. Nothing else about your plan changes.

Can staff text the dedicated number to report a problem?

Yes, and that's one of the main reasons to have one. A text sent to your dedicated number reaches your team by email, even if that phone never got an alert first.

Why would another sender affect our alerts on a shared number?

Mobile networks watch each sending number as a whole. If one account on a shared number sends something that looks like spam, the number can be filtered or blocked for a while. A dedicated number keeps your alarms out of that.

Put your alarms on a number of their own

One number, used only by your company, saved on every phone that matters.
