Guadeloupe island number rules: How to use 590

Guadeloupe is an overseas department of France, but its international dialing code is not 33, it is+590First, remember two key numbers:

• Domestic format (including leading 0): 10 digits, such as0590 XX XX XX(fixed),0690 XX XX XX(Move)
• International format (E.164): 9 digits after 590, a total of 12 digits, such as+590690000001

Guadeloupe shares 590 with French Saint Martin and Saint Barthelemy, which is the easiest pitfall to fall into.

Type	Domestic format (including leading 0)	International format (E.164)
Landline	0590 XX XX XX	+590590XXXXXX
Move (Common)	0690 XX XX XX	+590690XXXXXX
Move (Common)	0691 XX XX XX	+590691XXXXXX

Publicly available information shows that common prefixes for mobile numbers are 690 and 691, and common prefixes for landline numbers are 590. The main verifiable operators are Orange Caraïbe, Digicel (French West Indies), SFR Caraïbe, and Dauphin Telecom, which covers Saint Martin/Saint Barthelemy; the operator does not determine WhatsApp filtering results, as long as the number format is correct.

Number Standardization: Transform messy numbers into E.164 starting with 590

Clean before sieving. Target format:After 590, follow with 9 digits, remove spaces, parentheses, and hyphens, remove leading 0, replace 00 with。

Original input	Standardized results	Processing Instructions
0690000001	+590690000001	Remove the leading 0 from the mobile number
0590000001	+590590000001	Remove the leading 0 from the fixed number
+590 690 00 00 01	+590690000001	Remove spaces
590690000001	+590690000001	replenish
00 590 690 00 00 01	+590690000001	Replace 00 with

Excel cleaning logic reference (adjust function names according to your language version):

1. Remove spaces:=SUBSTITUTE(A1," ","")
2. Remove hyphens/brackets: continue nestingSUBSTITUTE
3. Starts with 00: Determine whether the first two digits are00, then replace with+
4. 0 at the beginning to be converted to international format: Check if the first digit is0, if so, remove it and add in front+590

Final verification rules:+590It must be 9 digits, not 8 digits, and not 10 digits.

Input example: How to prepare CSV

It is recommended to put phone numbers in the first column of the CSV in plain text format. The following is sample data,All are example numbers and not real users：

phone,country_code,note
590690000001,GP,Mobile 690 prefix
590590000001,GP,Fixed 590 prefix
590691000001,GP,Mobile 691 prefix

Enter directly in Excel+590...At times, it may be recognized as a formula and disappear. The solution is: first select the column and set it to ‘Text’, or use Excel’s ‘Data → Import’ function to import the CSV and specify the column as text. A TXT file with one number per line can also be uploaded directly.

Screen Open: Which numbers have registered on WhatsApp

Sift open to solve a problem:Is this number registered with a WhatsApp account?In the WhatsApp ecosystem, the number existence check only returns the registration status.

Taking the AppShai AppShai type of number screening platform as an example, the operating procedure is:

1. Upload the standardized number list (CSV/Excel/TXT)
2. Select the ‘WhatsApp’ platform
3. Create ‘Enable Filtering’ Task
4. Export the results after the task is completed

The output fields usually include: number, whether it is activated (activated/not activated), and detection time. Numbers that are not activated are filtered out directly, and activated ones proceed to the next step of active screening.

Screen active users: find target people among the numbers that have been activated

Activated ≠ Active. Many numbers remain unused for a long time after registration; this is what screening for activity is about.Filter out target accounts with recent online signals from the accounts that have been activated。

A common practice is to set a time window, such as ‘online within 7 days’ or ‘online within 30 days.’ Activity determination is based on observable signals (last online time, online status, online duration, etc.) and is affected by users’ privacy settings.Cannot achieve 100% accuracy, nor is there the term ‘permanently active.’ The activity results you see on the platform should be understood as activity estimates based on visible signals.

The platform supports enabling filters such as selection by activity, selection by online status, and selection by online duration, among others. The specific capabilities and thresholds are subject to the descriptions on the product page.

Results Explanation and Common Errors

A typical output result (sample values):

phone	registered	active	last_seen
+590690000001	yes	yes	2025-06-10 14:32 (UTC)
+590690000002	yes	no	2025-01-02 09:00 (UTC)
+590691000001	no	–	–

• registered=yesThe number has registered an account on WhatsApp
• active=yes: Online signals observed within the detection window
• last_seenEmpty: The user has hidden their last online time, or privacy settings make it impossible to verify

Common mistakes:

Phenomenon	Reason	Handle
Bulk display not activated	The area code is written incorrectly (such as mixing in 596 Martinique, 594 French Guiana numbers), or the digits following 590 are incorrect	Recheck according to 590 9 digits
The number disappears in Excel	Excel treats it as a formula	Set the cell to text format, or use the CSV import function to specify text columns
Number with spaces/hyphens causes unrecognition	Not standardized cleaning performed	Uniformly convert the format before uploading
The number of active users is very low	The number list is too old, the account has been deactivated	Update the data source, or relax the active time window

Local WhatsApp Usage and Compliance Considerations

Verifiable fact:

• Guadeloupe uses the French numbering plan,WhatsApp supports registration with 590 numbers, the user can verify with a local mobile number.
• In French Caribbean regions such as Guadeloupe, Martinique, and French Guiana, WhatsApp is one of the common cross-border communication tools.
• There is no reliable public data on the specific user scale, penetration rate, or usage preferences, so this article does not make any assumptions.

In terms of compliance, it is necessary to pay attention to:

• Guadeloupe belongs to the outermost regions of the European Union.GDPR applies to the processing of personal data。
• Number Checking is only allowed to be used for legally obtained data (proprietary CRM, user-authorized data, publicly available business information, etc.).
• Screening results are not to be used for unsolicited bulk messaging, harassment, or spam marketing.
• You must not attempt to bypass WhatsApp’s platform security mechanisms, message frequency limits, or verification processes.

Distinguishing Relevant Countries and Area Codes

590 is shared by three French territories, and there are several nearby area codes that are easily confused:

Region	International dialing code	Relationship with Guadeloupe
Guadeloupe (French)	+590	Area code of this article
French Saint Martin	+590	Shares the area code with Guadeloupe
Saint Barthélemy (French)	+590	Shares the area code with Guadeloupe
Martinique (French)	+596	Neighboring islands, easily confused
French Guiana (French)	+594	French territory in South America, easy to confuse
Dutch Sint Maarten	+1 721	The Dutch part of the island of Saint Martin,Not 590
Dominic	+1 767	Neighboring independent countries
Antigua and Barbuda	+1 268	Other countries in the same archipelago region

Quickly determine whether a number belongs to the Guadeloupe target range: first, check if it starts with 590, then see if there are 9 digits after 590, and finally confirm whether the mobile prefix is within common ranges such as 690/691. Following these three steps will basically avoid mistakes.
