Question

How to default at +1 for US phone number for a 30 minute event

Hi, I’m running into an issue with my calendly event, when a prospect starts entering a phone number as the location of the 30 minute event, they see a US flag but as soon as they start typing in the phone number (without the +1), the US flag goes away and prospect gets error on phone number stating missing country code.  Has anyone run into this before and if so, were you able to solve it and how? 

Let me know.  Thanks!

Will everyone be notified when it’s fixed? I’m having the same issue!

As a workaround until this is fixed you can prefill the “+1” in the link to ensure that it automatically shows the country code number in phone input. For example, using the link - https://calendly.com/d/cxpp-pt5-m4k?a3=+1 - will automatically show the “+1”.

You can add ?a3=+1 to your calendly url (make sure to change a3 to a1,a2, etc depending on which question number corresponds to the phone input).

First, I’m not a programmer person. Second, then what happens when it gets fixed?

If you are able to share your Calendly link I can update the link to include the “+1”. The instructions below explain how it works.

It continues to work the same - when the bug is fixed it’ll work exactly same whether the prefill is there or not.

This is a problem that appears to be over one year old! Does this mean that it has to be added manually to the link for each meeting? Or can this be embedded in the Calendly code, so that when new folks sign up they don't have this problem with the country code? If so, could you explain in a little more detail how to do that? I did read the support page that you referenced. BTW, since this issue appears to be over a year old, this would make an excellent tutorial video for your YouTube channel. Thank you very very much!!

Thank you! I am confused though, BC, I put the calendly info into Wordpress (we are a small company that uses calendly for our events—numerous ones daily—and I use the code “add to website” instead of copy link). How do I do this above step then? If I want to add it to the INLINE EMBED option? AND do I have to do this for every event? This seems INSANE! Is it smarter to set up a custom question for phone number and thrn off the calendly question? And again is that to be done for every event? We have multiple events daily!

Thank you everyone for your input. Based on the knowledge provided, I’m now able to get the 1 defaulted into the phone number (Thank you!), however, the + before the 1 does not default even though I included it on my link.  "https://calendly.com/my-calendar/?location=+1"

@Ed13213 - great callout! The location input works differently for some reason, so the “+” will not appear like in the custom questions.
 

@Sonia83470 - I’ve highlighted the code you need to change for the inline widget below; when you copy your code you’ll just need to add the “a3=+1” (or whichever answer corresponds to the input)

<!-- Calendly inline widget begin -->
<div class="calendly-inline-widget" data-url="https://calendly.com/acmesales?a3=+1" style="min-width:320px;height:700px;"></div>
<script type="text/javascript" src="https://assets.calendly.com/assets/external/widget.js" async></script>
<!-- Calendly inline widget end →

Do you have multiple embeds on your site? If so, there might be a way to programmatically add the “+1” to avoid needing to manually update everything. Feel free to email me directly if you’d prefer not to share your site publicly.

Omg can you please help me do this universally so it’s not needed for every single event?
