Notes On vCard VCF File Syntax Specifications

File Extension = .vcf
Commonly Referred To As: Address Book or Contacts

URI = Uniform Resource Identifier
Character Set is UTF-8
Elements are NOT Case Sensitive

For clarity, I Choose to define the following -

One STATEMENT appears on each line of the vCard file. (Provided there is not any line folding.)


According to the specification, an ELEMENT is any defined component of the syntax specification.
A new ELEMENT may be defined according IANA. (10.2) I refer to this as a CUSTOM element. The only custom elements I use are TYPE VALUES. Since TYPE is a reserved word in the syntax, I do not refer to “Types”, I refer to Type Values.


Line Folding requires white space at end of line to be ignored when the first character of the next line is white space.


Space Characters in Property Type Values will not export properly from the Samsung Galaxy S4. For example, using a custom type value of “My Membership” (without quotes) Will export as, TEL;:8005551212 . For this to work, you must include a hyphen character between words rather than a space character. This will then export correctly as, TEL;TYPE=X-My-Membership:8005551212 (vCard Version 2.1). Gmail will import this as “Other”. For Gmail to import properly, you must convert the Samsung export to the syntax accepted by Gmail, as follows,



Home, Work, Mobile, Cell (Converts to Mobile), Home Fax, Work Fax, Callback, Pref, Other, Custom
Home, Work, Pref, Other, Custom
Home, Work, Pref, Other, Custom
AIM, Yahoo, Skype, Windows Live, QQ, Hangouts, ICQ, Jabber, Custom
Birthday, Anniversary, Other, Custom
Assistant, Brother, Child, Father, Friend, Manager, Mother, Parent, Partner, Referred By, Relative, Sister, Spouse, Custom


TEL[;TYPE= type *[","type]]:
ADR[;TYPE= type*[","type]]:
EMAIL[;TYPE= type*[","type]]:


TEL;:7778884444 (NOTE: Omitting the colon will result in a failed import to the phone.)

Do Not Confuse Numbers with How They Are Dialed

As an example, in many countries the E.164 number “+1-212-555-3141″
will be dialed as 00-1-212-555-3141, where the leading “00″ is a
prefix for international calls. (In general, a “+” symbol in E.164
indicates that an international prefix is required.)

August 7th, 2013 · No Comments · Business and Management

Don’t bother searching their site search, or their FAQ.

Here’s how you (as Admin) can impersonate (or Alias) another user in project management online software. The purpose of impersonation is so you can make sure you set all their permissions correctly.

By impersonating their account, you can be sure you haven’t given them access to something private or confidential for your team.

Here are the simple instructions -

1. Login to your account as admin.

2. In the top left navigation menu, click on “People”.

Do Consumers Understand What the Word “Digital” Means?

June 24th, 2012 · 4 Comments · Marketing and Advertising, Online Business, Promotion, and Marketing, Web Development

As I ponder a domain name for my web development company, I suggested a name to a friend that has the word digital in it. He said he thinks it’s too broad a term and that we should focus on the words web development. So I began looking for articles that can tell me how familiar consumers are with the word “digital.”

For the most part, I was disappointed in my search. Nonetheless, here are some articles that do shed some light on the subject. [Read more →]

VMware Tools Keeps Windows Virtual Machine From Booting Slowly

June 12th, 2012 · No Comments · Computer Technology & Technical Support

After copying my virtual machine files to a backup and then I try to boot from it, that virtual machine can take more than 1-1/2 minutes to get past the Windows Welcome screen.

Generally, re-installing VMware Tools will fix this problem. However, when I attempted this for the first time, I was not able to get the installation to work. [Read more →]
