Phone Number masking plugin in react native



There is a great npm plugin for implementing phone number masking, so let’s start to implement

  • Step1: First we need to install the plugin


npm install react-native-masked-text –save
  • Step2: Now start to import the plugin in which page you want to implement this


import{ TextInputMask }from'react-native-masked-text'
  • Step3: There is 2 type of phone number masking 

         1) BRL (default): (99) 9999-9999 or (99) 99999-9999 (will detect automatically)

         2)INTERNATIONAL: +999 999 999 999


this.state={mobile:''//must be assigned empty string}
maskType: 'BRL',//for international set it -&amp;nbsp;INTERNATIONAL type masking
withDDD: true,
dddMask: '(999) 999-9999'//this is a your define formatting you use according to your requirment
maxLength={14}//set length according to your input requirment
placeholder={'Mobile Number'} 
onChangeText={(mobile) =>this.setState({ mobile })}
style={styles.input} ref='mobile'
  • Step4: we also able to set the option


maskTypestringnomaskTypethe type of the mask to use. Available: BRL or INTERNATIONAL
withDDDbooleannotrueif the mask type is BRL, include the DDD
dddMaskstringno(99)if the mask type is BRL, the DDD mask
  • Step4: you can also able to get the unmasked value by using getRawValue()
const  unmasked = this.phoneField.getRawValue()

exp: in the mask: (51) 98765-4321

unmasked: 51987654321

Expected error: TypeError: text.replace is not a function react-input-mask

Reason: if you did not declare a state of a mobile blank string
