Your website's clickable phone number is powered by a line of code called a tel: link. Most Rhode Island sites use a local format like tel:401-123-4567 — which works fine for most local callers, but can silently fail for VoIP users, non-US SIM cards, and Google Ads. The fix is simple: use the E.164 international standard — tel:+14011234567 — on every phone link. It works everywhere the local format works, and then some. If your business has any international exposure or runs Google Shopping ads, this isn't optional.

There's a small piece of code behind every clickable phone number on your website. Most Rhode Island businesses don't know it exists — and a surprising number have it formatted in a way that can cause calls to fail without any warning.

Here's what's happening and how to fix it.

Three Formats, One Number

When you click a phone number on a website, you're not typing anything. Your device reads a line of code and passes it directly to your dialer. That HTML programming could look like one of these:

tel:401-123-4567 — the common local format
tel:401.295.1234 — dots as separators, equally common, equally incomplete
tel:+14011234567 — the E.164 international standard

The first two are variations of the same problem. The third is the one that works everywhere.

The E.164 format includes +1 — the country code shared by the United States, Canada, and parts of the Caribbean — which tells any device, anywhere, exactly where to route the call- followed by ten phone digits without spaces, hyphens, or any other separator. This isn't a preference or a best practice recommendation. The governing standard for phone number links on websites, IETF RFC 3966 (authored by Columbia University professor Henning Schulzrinne), states it plainly.

"On a public HTML page, the telephone number in the URI SHOULD always be in the global form, even if the text of the link uses some local format."

Note: That URI is your tel: link and the global form is E.164.

Why It Matters

For most of your local customers calling from a Rhode Island smartphone, either format works fine. The native dialer figures it out.

But for some callers, a problem happens quietly, in the background:

Non-US SIM cards — A visitor using a UK, Mexican, or Japanese SIM card — physically here in Rhode Island — has a device whose dialing context is tied to their home country, not their current location. Without the +1 country code in your link, their device may have no instruction to route the call to the US. Whether it connects depends on their carrier and device — and you have no control over either.
VoIP and business calling apps — Microsoft Teams, RingCentral, Zoom Phone. These platforms are stricter than native dialers and may reject a number without a country code entirely.
Google Ads and Google Merchant Center — E.164 is required for call assets in Google Ads, and actively verified in Google Merchant Center. For e-commerce businesses, a phone number that fails Merchant Center verification can suspend your entire product catalog — not just a single ad. If you're running Shopping ads, this is a must-fix, not a maybe.

The defining characteristic of all three: they fail silently. No error. No callback. Just a missed opportunity.

This Is a Must-Fix If You Have International Exposure

If your business attracts visitors, buyers, or partners from outside the United States — even occasionally — this is not optional.

If any of the following describes your business, E.164 is the only format you should be using:

Government agencies and public institutions
Marine and maritime businesses
Manufacturers and industrial companies
Healthcare providers
Hospitality and tourism
Academic institutions
Law firms — especially immigration, maritime, and international business
Real estate — foreign buyers in coastal New England are a growing market
Financial services and wealth management
Event venues and the wedding industry
Recruiting and staffing agencies
Ports, freight, and logistics
E-commerce or B2B companies that ship or sell beyond US borders

A non-US device tapping a locally formatted phone link may have no instruction to dial the US. The call doesn't connect, and you'll never know it happened.

A Note for Web & Content Developers

Here's a small detail that's easy to standardize and worth integrating into your work. Adopting E.164 as your default phone number format — on every project, from the start — guarantees connectivity across every device, carrier, and calling platform your clients' customers will ever use. It costs nothing extra, takes no additional time, and quietly eliminates an entire category of call failures before they can happen. tel:+14011234567 works everywhere tel:401-123-4567 works mostly - but why risk it? Making it your studio standard is one of those small decisions that adds up to a better product — and a client who never has to call you about a broken phone link.
